Called "Porte de Haut" or "Porte Jeanne d'Arc" in memory of her passage in December 1430, it is one of the oldest vestiges of the city. The towers, dated from the 11th century, already existed during the forced stopover of William of Normandy's fleet in 1066. The ensemble consisted of two massive round towers, with brackets and machicolations, two buildings with one floor and underground passages that served as guardhouses and prisons, a drawbridge that disappeared in 1614, and advanced defense works that have now disappeared. The ogival archway was built in 1785 and a section of the curtain wall still remains. On the walls grows in summer a pink carnation called "the carnation of the crusades".
