Palais du Grabatoire, Episcopal palace in Plantagenet City, Le Mans, France.

Palais du Grabatoire is an episcopal palace in Le Mans featuring a distinctive facade with three stacked windows and two polygonal towers. These towers provide vertical access through the building and create its recognizable architectural form.

Begun in the 1520s for a canon of the Saint-Julien chapter, the house was completed after a transaction of 30 December 1542 between Anselme Taron and the chapter, which covered most of the cost. In 1562, after the cathedral was sacked by Protestants, a chapter room was set up here; in 1567 the attics stored grain for the town. In 1612 Marshal de Lavardin received the young Louis XIII and Marie de Medici, who was treated in the building.

The building's name probably comes from an earlier hospital on the site, and locals shorten it to Grabatoire or hôtel du Grabatoire. It was built from the 1520s for a member of the Saint-Julien chapter, and in 1562, after the cathedral was sacked by Protestants, a chapter room was set up here. The stone mullions and transoms dividing the windows were restored in the early 20th century after disappearing in the 18th.

The building stands at Cardinal-Grente square directly facing Saint-Julien Cathedral, making it easy to locate. Since it remains a private residence, visitors should confirm access conditions with the owners before planning a visit.

The building was long left unfinished: the dormers planned in the 16th century were only added in 1906, when Abbé Bruneau, who had bought it in 1895, also had two small bell turrets built at the base of the roof of the large turret. The 2014 restoration by heritage architect Laurent Cohin restored its render coating.
