This chapel is in the estate of the Chateau de Vincennes. It was started in 1379, but wasn't inaugurated until 1552 due to various wars and lack of money getting in the way of construction.
Today, it has recently been restored after severe damage by a storm in 1999. The outside is, in my opinion, the most impressive bit. The inside, although it has a lovely vaulted roof, is extremely plain and houses an exhibition of propaganda posters from 20th century. - Lucy
