This former Marais townhouse, now a museum, houses the collections of art lovers Ernest Cognacq and Marie-Louise Jay. During his lifetime, the founder of the Samaritaine bought numerous 18th-century European works. Paintings, sculptures, precious objects, drawings, porcelain, everyday objects from the Age of Enlightenment... Ernest Cognacq had an eye and a taste for exceptional works of art, which can now be admired at leisure in his museum. These include paintings by Rembrandt, Watteau, Fragonard, François Boucher, Canaletto, Houdon. ..

During this Nuit des Musées, we'll be strolling among these must-see works of art, and taking advantage of the unique events organized for this special night.
