The Joan of Arc Tower, located close to the train station in Rouen, is an interesting sight to see among the more modern buildings in the area. The tower is actually the only surviving part of a medieval castle that was built in the 13th century. More significantly, this is the tower where Joan of Arc was imprisoned and interrogated before she was burned at the stake for heresy in 1431. Today, the tower is open to the public as a museum. I honestly didn't realize that Rouen had such a large part in the history surrounding Joan of Arc until we arrived in city and began walking around the streets. This imposing tower was one of the first things we noticed.
