Guillaume Robin

As early as 1435, René d'Anjou asked his project manager, Robin, to double the size of his royal dwelling of the Château d'Angers with a gallery whose staircase bears his motto on the vault.

[1] In 1453, Robin redid the paving of the transept north of the Saint-Maurice Catheral of Angers.

He also built in the cathedral the right handstaircase to provide access to the library in the south transept.

In 1454, at the end of the Hundred Years' War, René of Anjou inherited the ruins of his mother's castle in the town of Le Vieil-Baugé, still glowing with the French victory at the Battle of Baugé.

He built a hunting lodge the size of a manor house, which became the Château de Baugé.
