I passed through Gisors several times without stopping.
I corrected this error. Gisors is a pleasant old town, with an impressive
ancient Castle when the king of France and the king of England were at
war at the end of the 11th century.
My lunch, in some kind of Bistrot, was very simple, but cheap, good
quality and tasty. It was a good day trip.
From Paris, you reach Gisors in slightly more than one hour by train
(Saint Lazare station). Schedule:
