The Palace of Tau in Reims, was the palace of the Archbishop of Reims. It is associated with the kings of France, whose coronation was held in the nearby cathedral of Notre-Dame de Reims and the following coronation banquet in the palace itself. Because of its historical importance for the French monarchy, the Palace of Tau was inscribed on the UNESCO World Heritage List in 1991. Today, it serves to host cultural events for the city of Reims.
A large Gallo-Roman villa still occupied the site of the palace in the 6th and 7th centuries, and later became a Carolingian palace. The first documented use of the name dates to 1131, and derives from the plan of the building, which resembles the letter Τ (tau, in the Greek alphabet). Most of the early building has disappeared: the oldest part remaining is the chapel, from 1207. The building was largely rebuilt in Gothic style between 1498 and 1509, and modified to its present Baroque appearance between 1671 and 1710 by Jules Hardouin-Mansart and Robert de Cotte. It was damaged by a fire on 19 September 1914, and not repaired until after the Second World War.
The Palace was the residence of the kings of France before their coronation in Notre-Dame de Reims. The king was dressed for the coronation at the palace before proceeding to the cathedral; afterwards, a banquet was held at the palace. The first recorded coronation banquet was held at the palace in 990, and the most recent in 1825.
The palace has housed the Musée de l'Œuvre since 1972, displaying statuary and tapestries from the cathedral, together with the remains of the cathedral treasury and other objects associated with the coronation of the French kings.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
