 The château was originally a fortified manor dating back to 1368 and, although amputated of its eastern wing at the time of Napoleon, it still retains its pentagonal bastioned footprint.King Francis I died there, on 31 March 1547, probably in the imposing medieval tower that bears his name.Like the Hôtel de Rambouillet in Paris, the château was owned by Charles d'Angennes, the marquis de Rambouillet during the reign of Louis XIII.
