it is recorded as having been converted into a cistern in 1541. It was designed by an architect named Miguel de Arruda but the construction work was delegated to João de Castilho. A round opening in the center of the chamber served to collect rainwater. The cistern is famous especially for the thin layer of water that covers the floor and creates fine and ever-changing reflections in the otherwise dark vaulted chamber. Its visual qualities are such that several movies have been filmed within the cavernous space, of which Orson Welles' Othello is the best known internationally. Churches The Church of Our Lady of the Assumption, a prominent building located south of the Citadel, was the main parish church of the Portuguese settlement. It was constructed or begun when the fortress was expanded in 1541. It has a nave, a choir, a sacristy, and a square-shafted bell tower. At least three other churches existed, though generally only partial remains of them are still present today. Two small churches were adjoined to some of the bastions of the fortress. Another, the Church of Mercy (Misericórdia) was part of the Citadel. Synagogues A number of synagogues also existed inside the old city, attesting to the importance of the Jewish community here in the 19th and 20th centuries. One prominently visible example is the Bensimon Synagogue, inaugurated in 1926 and attached to earlier structures in the northern corner of the former fortress. Its construction was sponsored by four brothers of the Bensimon family: Nessim, Messaoud, Abraham, and Mordechai. Museum of Resistance and Independence Located near the beach south of the old city and the port, this museum and exhibition space is dedicated to the memory of Moroccan soldiers and resistance to the French Protectorate regime. It is housed in a 20th-century colonial era building constructed in a "Mauresque" style. Climate El Jadida has a hot-summer Mediterranean climate (Köppen climate classification Csa).

Economy The city is a significant tourism destination thanks in part to its UNESCO-recognized historic heritage. A large five-star resort, the Mazagan Beach Resort, was opened in 2009 besides the nearby town of Azemmour, named in reference to the historic Portuguese fort. The resort was part of a wider strategy launched in 2001 by King Mohammed VI to boost
