San Juan de Ulua is a maze of historic fortresses and prison cells on a shadowy island overlooking the once-busy port of Veracruz. Constructed in 1956, the fort is home to a dark history that includes captured naval fleets, African slave trade and international treasure.
During the nineteenth century the imposing stone walls and deep dungeons of San Juan de Ulua served as a prison for Mexican political activists. The views from the old lookout tower make it a popular attraction, but a hidden chapel on the southwest side of the structure, massive treasure storage rooms and the dungeon of San Juan de Ulua, which housed the legendary bandit Chucho el Roto, are also worth a look.
The fortress is located at Pedro Saenz de Baranda S/N, in Ver Centro1, within walking distance of Arsenal Nacional. Admission is about 41 pesos per person and hour-long guided tours cost 300 pesos. The fortress is open Tuesday through Sunday from 9 a.m. until 4:30 p.m.
