Palais du Tau

Called Tau for its distinctive T shape, this palace has played an integral role in France's history for more than a millennia. It once belonged to the Archbishop of Reims and underwent multiple renovations over the centuries – most notably by Louis XIV's architects. Despite suffering heavy damage during WWI, the palace has been rebuilt to its original splendor. Today, you can step inside and admire the vaulted ceilings, see the older Gothic elements, and enjoy its manicured gardens.
