Palais du Tau by Tom_Fields
The Palais du Tau, or Palace Museum, is a former bishop's residence, now a museum of ecclesiastical life. It's so named because its layout forms a T shape, with "tau" being the Greek letter T. This is where French kings prepared for their coronation ceremonies, and held their banquets afterwards. Burned in World War I, it was restored after World War II. It has some interesting exhibits and examples of medieval tapestries and other artwork.
