Situated in the old episcopal palace, it takes its name from the famous orator and theologian, Jacques-Bénigne Bossuet, Bishop of Meaux from 1681 to 1704.

The most interesting example of eighteenth century work is the south facade of the palace, built of brick and stone, with large cross windows.

The episcopal palace houses collections of paintings and sculptures, as well as items of local history.

The collections have expanded thanks to the legacy of the chemist and collector Henri Moissan in 1914 and, more recently, thanks to the donation of the neuro-biologist Jean-Pierre Changeux.

The memory of Bishop Bossuet of Meaux (1682-1704) is evoked by his portraits by Hyacinthe Rigaud and after Pierre Mignard gathered in his old study.
