[1] The Hôtel de Sully was built, with gardens and an orangery, between 1624 and 1630, for the wealthy financier Mesme Gallet.

The Marais was then an especially fashionable area for the high nobility ; the construction of the Hôtel de Sully fits in a larger movement of monumental building in this part of Paris.

[3] Maximilien de Béthune, Duke of Sully, and former Superintendent of Finances to King Henri IV, purchased the hôtel, completed and fully furnished, on 23 February 1634.

His grandson Maximilien commissioned architects, most probably Simon Lambert and François Le Vau, to build an additional wing in 1660, to the west of the garden.

This public body, under the supervision of the Ministry of Culture and Communication, is responsible for the management of historic buildings and monuments in state care.
