Inside the 800 m-long enclosure, discover the castle keep and its surrounding walls, built on an impressive artificial motte castrale 30 m high and 70 m in circumference.
The Barbacane is the castle’s forecourt at the northeast corner of the enclosure. Access to the castle used to be via the Barbacane, a defensive structure leading to the Passage du Monarque, where the tourist office is located. The barbican is surrounded by curtain walls, the Governor’s Tower and the imposing circular keep built by Philippe Auguste, known as the Prisoner’s Tower.
Superb and mysterious engravings adorn the interior walls of the Tour du Prisonnier.
Every even-numbered year, “Gisors, La Légendaire” celebrates this exceptional heritage with a medieval festival of discovery and immersion in all facets of life in the Middle Ages.
