The Basilica of Constantine (Konstantinbasilika or Aula Palatina) is a Roman palace basilica that was built by the emperor Constantine (AD 306–337) at the beginning of the 4th century.
Today it is used as a church and owned by a congregation within the Evangelical Church in the Rhineland. The basilica contains the largest extant hall from antiquity with a length of 67 m, a width of 26.05 m 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 Basilica 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 incorporating it into his palace some major redesign was done. 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.References:
Kroměříž stands on the site of an earlier ford across the River Morava. The gardens and castle of Kroměříž are an exceptionally complete and well-preserved example of a European Baroque princely residence and its gardens and described as a UNESCO World Heritage Site.
The first residence on the site was founded by bishop Stanislas Thurzo in 1497. The building was in a Late Gothic style, with a modicum of Renaissance detail. During the Thirty Years' War, the castle was sacked by the Swedish army (1643).
It was not until 1664 that a bishop from the powerful Liechtenstein family charged architect Filiberto Lucchese with renovating the palace in a Baroque style. The chief monument of Lucchese's work in Kroměříž is the Pleasure Garden in front of the castle. Upon Lucchese's death in 1666, Giovanni Pietro Tencalla completed his work on the formal garden and had the palace rebuilt in a style reminiscent of the Turinese school to which he belonged.
After the castle was gutted by a major fire in March 1752, Bishop Hamilton commissioned two leading imperial artists, Franz Anton Maulbertsch and Josef Stern, arrived at the residence in order to decorate the halls of the palace with their works. In addition to their paintings, the palace still houses an art collection, generally considered the second finest in the country, which includes Titian's last mythological painting, The Flaying of Marsyas. The largest part of the collection was acquired by Bishop Karel in Cologne in 1673. The palace also contains an outstanding musical archive and a library of 33,000 volumes.
UNESCO lists the palace and garden among the World Heritage Sites. As the nomination dossier explains, 'the castle is a good but not outstanding example of a type of aristocratic or princely residence that has survived widely in Europe. The Pleasure Garden, by contrast, is a very rare and largely intact example of a Baroque garden'. Apart from the formal parterres there is also a less formal nineteenth-century English garden, which sustained damage during floods in 1997.
Interiors of the palace were extensively used by Miloš Forman as a stand-in for Vienna's Hofburg Imperial Palace during filming of Amadeus (1984), based on the life of Wolfgang Amadeus Mozart, who actually never visited Kroměříž. The main audience chamber was also used in the film Immortal Beloved (1994), in the piano concerto scene.
