Aula Palatina

The Basilica of Constantine (German: Konstantinbasilika), or Aula Palatina, at Trier, Germany is a Roman palace basilica that was commissioned by the emperor Constantine I (AD 306–337) at the beginning of the 4th century.

Today it is used as the Church of the Redeemer and owned by a congregation within the Evangelical Church in the Rhineland. The basilica contains the largest extant hall from antiquity (see List of ancient Greek and Roman roofs) and is ranked a World Heritage Site. The hall has a length of 67 m, a width of 26.05 m[1] and a height of 33 m. It is designated as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site.

The Aula Palatina was built around AD 310 as a part of the palace complex. Originally it was not a free standing building, but had other smaller buildings (such as a forehall, a vestibule and some service buildings) attached to it. The Aula Palatina was equipped with a floor- and wall-heating system (hypocaust).

During the Middle Ages, it was used as the residence for the bishop of Trier. For that, the apse was redesigned into living quarters and pinnacles were added to the top of its walls. In the 17th century, the archbishop Lothar von Metternich constructed his palace just next to the Aula Palatina and incorporated it into his palace doing some major redesign. Later, in the 19th century, Frederick William IV of Prussia ordered the building to be restored to its original Roman state, which was done under the supervision of the military architect Carl Schnitzler. In 1856, the Aula Palatina became a Protestant church. In 1944, the building burned due to an air raid of the allied forces during World War II. When it was repaired after the war, the historical inner decorations from the 19th century were not reconstructed, so that the brick walls are visible from the inside as well.

Architecture of Germany

The architecture of Germany has a long, rich and diverse history. Every major European style from Roman to Post Modern is represented, including renowned examples of Carolingian, Romanesque, Gothic, Renaissance, Baroque, Classical, Modern and International Style architecture.

Centuries of fragmentation of Germany into principalities and kingdoms caused a great regional diversity and favoured vernacular architecture. This made for a heterogeneous and diverse architectural style, with architecture differing from town to town. While this diversity may still be witnessed in small towns, the devastation of architectural heritage in the larger cities during World War II resulted in extensive rebuilding characterized by simple modernist architecture.

A word for the auditorium in a school or university in many European languages


The Latin word basilica (derived from Greek: βασιλική στοά, Royal Stoa, the tribunal chamber of a king) has three distinct applications in modern English. Originally, the word was used to refer to an ancient Roman public building, where courts were held, as well as serving other official and public functions. It usually had the door at one end and a slightly raised platform and an apse at the other, where the magistrate or other officials were seated. The basilica was centrally located in every Roman town, usually adjacent to the main forum. Subsequently, the basilica was not built near a forum but adjacent to a palace and was known as a "palace basilica".

As the Roman Empire adopted Christianity, the major church buildings were typically constructed with this basic architectural plan and thus it became popular throughout Europe. It continues to be used in an architectural sense to describe rectangular buildings with a central nave and aisles, and usually a raised platform at the opposite end from the door. In Europe and the Americas the basilica remained the most common architectural style for churches of all Christian denominations, though this building plan has become less dominant in new buildings since the latter 20th century.

Thirdly, the term refers specifically to an official designation: a large and important Catholic church that has been given special ceremonial rights by the Pope, whatever its architectural plan. These are divided into four major basilicas, all of which are ancient churches located within Rome, and, as of 2017, 1,757 minor basilicas around the world.Some Catholic basilicas are Catholic pilgrimage sites, receiving tens of millions of visitors per year. In December 2009 the Basilica of Our Lady of Guadalupe set a new record with 6.1 million pilgrims during Friday and Saturday for the anniversary of Our Lady of Guadalupe.


A brick is building material used to make walls, pavements and other elements in masonry construction. Traditionally, the term brick referred to a unit composed of clay, but it is now used to denote any rectangular units laid in mortar. A brick can be composed of clay-bearing soil, sand, and lime, or concrete materials. Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. Two basic categories of bricks are fired and non-fired bricks.

Block is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate.

Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since circa 4000 BC. Air-dried bricks, also known as mudbricks, have a history older than fired bricks, and have an additional ingredient of a mechanical binder such as straw.

Bricks are laid in courses and numerous patterns known as bonds, collectively known as brickwork, and may be laid in various kinds of mortar to hold the bricks together to make a durable structure.

Electoral Palace, Trier

The Electoral Palace (German: Kurfürstliches Palais) in Trier, Germany, was the residence of the Archbishops and Electors of Trier from the 16th century until the late 18th century. It now houses various offices of the federal government and often hosts classical music concerts.

Electorate of Trier

The Electorate of Trier (German: Kurfürstentum Trier or Kurtrier), traditionally known in English by its French name of Trèves, was an ecclesiastical principality of the Holy Roman Empire that existed from the end of the 9th to the early 19th century. It consisted of the temporal possessions of the prince-archbishop of Trier (Erzbistum Trier), also prince-elector of the empire. There were only two other ecclesiastical prince-electors in the Empire: the Electorate of Cologne and the Electorate of Mainz, among which Mainz ranked first.

The capital of the electorate was Trier, with the main residence of the Elector being Koblenz from the 16th century onward. The electorate was secularized in 1803 during Napoleonic rule.

The Elector of Trier, in his capacity as archbishop, also administered the archdiocese of Trier, whose territory did not correspond to the electorate (see map below).

Forced perspective

Forced perspective is a technique which employs optical illusion to make an object appear farther away, closer, larger or smaller than it actually is. It manipulates human visual perception through the use of scaled objects and the correlation between them and the vantage point of the spectator or camera. It has applications in photography, filmmaking and architecture.

History of Trier

Trier in Rhineland-Palatinate, whose history dates to the Roman Empire, is often claimed to be the oldest city in Germany. Traditionally it was known in English by its French name of Treves.

List of Brick Romanesque buildings

Brick Romanesque (German: Backsteinromanik) is an architectural style and chronological phase of architectural history. The term described Romanesque buildings built of brick; like the subsequent Brick Gothic, it is geographically limited to Northern Germany and the Baltic region. Structures in other regions are not described as Brick Romanesque but as "Romanesque brick-built church" or similar terms.

In comparison to Brick Gothic, Brick Romanesque is a less established and less frequently used term. On the one hand, this is caused by the fact that the Baltic region was only beginning to develop its own stylistic identity during the Romanesque period, on the other by the relatively low number of surviving buildings. Many of the major Brick Gothic edifices had Brick Romanesque predecessors, remains of which are often still visible. Nearly all preserved buildings are churches. The buildings contrast with earlier stone-built churches (Fieldstone churches or Feldsteinkirchen), which were constructed of glacial erratics and rubble. Such rounded stones limit the potential size of a building; the material and technique do not permit the construction of structures larger than a village church for static reasons. Monumental constructions only became possible through the growing use and perfection of brick building.

List of oldest known surviving buildings

This article lists the oldest known surviving free-standing buildings constructed in the world, including on each of the continents and within each country.

"Building" is defined as any human-made structure used or interface for supporting or sheltering any use or continuous occupancy. In order to qualify for list a structure must:

be a recognisable building;

incorporate features of building work from the claimed date to at least 1.5 metres (4.9 ft) in height;

be largely complete or include building work to this height for most of its perimeter.

contains an enclosed area with at least one entry point.This consciously excludes ruins of limited height and statues. The list also excludes:

dolmens—a type of single-chamber megalithic tomb, usually consisting of three or more upright stones supporting a large flat horizontal capstone. Dolmens were typically covered with earth or smaller stones to form a tumulus (which are included in the list). In many instances, that covering has weathered away, leaving only the stone "skeleton" of the burial mound intact. Neolithic dolmens are extremely numerous, with over 1,000 reported from Mecklenburg-Vorpommern in Germany alone.

cairns which are simply large piles of loose stones (as opposed to chambered cairns.)Dates for many of the oldest structures have been arrived at by radiocarbon dating and should be considered approximate.

Old St. Peter's Basilica

Old St. Peter's Basilica was the building that stood, from the 4th to 16th centuries, where the new St. Peter's Basilica stands today in Vatican City. Construction of the basilica, built over the historical site of the Circus of Nero, began during the reign of Emperor Constantine I. The name "old St. Peter's Basilica" has been used since the construction of the current basilica to distinguish the two buildings.

Palace of Aachen

The Palace of Aachen was a group of buildings with residential, political and religious purposes chosen by Charlemagne to be the centre of power of the Carolingian Empire. The palace was located at the north of the current city of Aachen, today in the German Land of North Rhine-Westphalia. Most of the Carolingian palace was built in the 790s but the works went on until Charlemagne's death in 814. The plans, drawn by Odo of Metz, were part with the programme of renovation of the kingdom decided by the ruler. Today much of the palace is destroyed, but the Palatine Chapel has been preserved and is considered as a masterpiece of Carolingian architecture and a characteristic example of architecture from the Carolingian Renaissance.

Religion in Germany

Christianity is the largest religion in Germany, comprising an estimated 57% of the country's population in 2017. The second largest religion in Germany is Islam, with around 4 million adherents (5% of the population), almost all of them have full or partial foreign background. Smaller religious groups include Buddhism (0.2%), Judaism (0.1%), Hinduism (0.1%) and others (0.4%). About 36–37% of the country's population are not affiliated with any church or religion.The two largest Christian churches of the country are the Roman Catholic Church and the Evangelical Church in Germany (EKD), a Protestant confederation of United Protestant (Lutheran and Reformed) churches. The two churches together comprised 54% of the population in 2017, of whom 28.2% belonged to the Catholic Church and 26.1% to the Evangelical Church. In 2016, the Orthodox Church constituted ~2% of the population and other minor Christian churches (including Jehovah's Witnesses, The Church of Jesus Christ of Latter-day Saints, other Protestant denominations, and others), formed 1–1.5%.Demographics of religion in Germany vary greatly by region and age. A majority of Germans under 25 years-old claim to not believe in any religion. Non-religious people (including atheists and agnostics) represent the majority in some of Germany's major cities, including Berlin and Hamburg, and the absolute majority of 70–80% of the population in all the eastern states of what between 1949 and 1990 used to be the German Democratic Republic; by contrast, rural areas of the western states of what in the same period used to be the Federal Republic of Germany are more religious, and some rural areas are highly religious.

Roman Monuments, Cathedral of St Peter and Church of Our Lady in Trier

The Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier, Germany was listed as a UNESCO World Heritage site (WHS) in 1986.From UNESCO/CLT/WHC:

"Trier is an example of a large Roman capital after the division of the empire. The remains of the Imperial Palace, in addition to the Aula Palatina and the Imperial Thermae, are impressive in their dimensions. The city bears exceptional testimony to Roman civilization owing to the density and the quality of the monuments preserved: the bridge, the remains of the fortified wall, thermae, amphitheatre, storehouses, etc. In particular, funerary art and the craftsmanship of potters, glassworkers, and moneyers flourished in the city."

Tourism in Germany

Germany is the ninth most visited country in the world, with a total of 407.26 million overnights during 2012. This number includes 68.83 million nights by foreign visitors, the majority of foreign tourists in 2009 coming from the Netherlands, the United Kingdom, and Switzerland (see table). Additionally, more than 30% of Germans spend their holiday in their own country.

According to Travel and Tourism Competitiveness Reports, Germany is ranked 3 out of 136 countries in the 2017 report, and is rated as one of the safest travel destinations worldwide.

In 2012, over 30.4 million international tourists arrived in Germany, bringing over US$38 billion in international tourism receipts to the country. Domestic and international travel and tourism combined directly to contribute over EUR43.2 billion to the German GDP. Including indirect and induced impacts, the industry contributes 4.5% of German GDP and supports 2 million jobs (4.8% of total employment). The ITB Berlin is the world's leading tourism trade fair.According to surveys, the top three reasons for tourists to come to Germany, are the German culture, outdoor activities and countryside, and the German cities.


Trier (German pronunciation: [tʁiːɐ̯] (listen); Luxembourgish: Tréier [ˈtʀəɪ̯ɐ]), formerly known in English as Treves (French: Trèves, IPA: [tʁɛv]) and Triers (see also names in other languages), is a city in Germany on the banks of the Moselle. Trier lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region. The German philosopher and one of the founders of Marxism, Karl Marx was born in the city in 1818.

Founded by the Celts in the late-4th century BC as Treuorum, it was later conquered by the Romans in the late-1st century BC and renamed Trevorum or Augusta Treverorum (Latin for "The City of Augustus among the Treveri"). Trier may be the oldest city in Germany. It is also the oldest seat of a bishop north of the Alps. In the Middle Ages, the Archbishop-Elector of Trier was an important prince of the church, as the archbishop-electorate controlled land from the French border to the Rhine. The Archbishop-Elector also had great significance as one of the seven electors of the Holy Roman Empire.

With an approximate population of 105,000, Trier is the fourth-largest city in its state, after Mainz, Ludwigshafen, and Koblenz. The nearest major cities are Luxembourg (50 km or 31 mi to the southwest), Saarbrücken (80 kilometres or 50 miles southeast), and Koblenz (100 km or 62 mi northeast).

The University of Trier, the administration of the Trier-Saarburg district and the seat of the ADD (Aufsichts- und Dienstleistungsdirektion), which until 1999 was the borough authority of Trier, and the Academy of European Law (ERA) are all based in Trier. It is one of the five "central places" of the state of Rhineland-Palatinate. Along with Luxembourg, Metz and Saarbrücken, fellow constituent members of the QuattroPole union of cities, it is central to the greater region encompassing Saar-Lor-Lux (Saarland, Lorraine and Luxembourg), Rhineland-Palatinate, and Wallonia.
