On the border between the 17th and the 8th arrondissement is the Monceau district. Located a stone's throw from Parc Monceau, in a mansion, is the Cernuschi Museum of Asian Arts. Henri Cernuschi, a great collector, bequeathed all his works to the Mairie de Paris. Another museum not to be missed is the Jacquemart-Andrée museum. On Daru Street is the St. Alexander Nevsky Orthodox Cathedral, built-in 1861. This monument, of Byzantine architecture inside and Moscow outside, is worth a visit. It is here that Picasso married his famous companion Olga in 1918, with witnesses who are none other than Jean Cocteau, Max Jacob, or Guillaume Apollinaire... But the Monceau district is also and above all the magnificent park Monceau, a refuge for walkers in search of peace and pleasure.
