The Chateau de Vincennes allows you to understand the historical diversity of this city-museum that is Paris. In Vincennes, next to Paris, on the east side, at the metro stop of the same name, stands the Castle of Vincennes, built in the fourteenth century by the kings of France. Surrounded by a wall, which encloses the town in the style I studied in school ;), There are different buildings (a chapel, a tower, several outbuildings), recent renovations allow you to enjoy the town which I loved for its cleanliness and grand appearance . For the normal price of 8 euros, unfortunately the visit (at least when I went) only includes a visit to the tower, and outdoor patios - some buildings are now occupied by the department of defence and other public institutions which restrict access . If you are lucky one of the side doors in the wall may be open, and you may be able to enter the courtyard without paying an entrance fee (who knows ;) Still, this offer another point of view on the history of the capital, and the Bois de Vincennes is just beside to enjoy a picnic or a walk. This is an excellent way to spend a day off!
