The palace of tau" A large Gallo-Romanvilla 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.
