The Portuguese Cistern, El Jadida
A 16th-century Gothic vault, a thin film of still water, and one of Morocco’s most arresting reflections — the underground monument that Orson Welles made famous.

Descend a short staircase beneath El Jadida’s old Portuguese quarter and you step into one of the most quietly astonishing spaces in Morocco. The cistern is not grand in scale — roughly the footprint of a tennis court — but its five aisles of slender Gothic columns rise into vaulted arches and then disappear into their own perfect reflections in the shallow water that pools across the floor. The single skylight overhead throws a shifting column of light that makes the stone look almost luminous. You find yourself whispering.
Built by the Portuguese around 1514 as a water reservoir for the fortified colony of Mazagan, the cistern was largely forgotten after Portugal abandoned the city in 1769. It was rediscovered and partially flooded by the sea water that had seeped in over two centuries — and that accidental flooding turned a utilitarian tank into something extraordinary. Orson Welles recognised it immediately when he came to Morocco in the early 1950s, short of funds and looking for locations for his adaptation of Othello. Several scenes — widely credited as the film’s most visually striking — were shot here, and the Palme d’Or the film won at Cannes in 1952 partly rests on this crypt’s bones.
El Jadida remains one of Morocco’s less-visited cities, which makes the cistern a rare thing: a genuinely spectacular site you can often have almost to yourself.

Photography tip: The magic shot — columns reflected in the floor water, shaft of skylight overhead — works best on a clear morning between about 09:30 and 11:30. Bring a wide-angle lens or use your phone’s ultra-wide; the space is intimate and you cannot step far back. A small torch helps in the darker corners.
The Cité Portugaise ramparts enclose the entire walled medina — the cistern lies at its heart.
The Orson Welles Connection
When Welles began shooting Othello in 1949 he had a clear visual ambition and a chronically unreliable budget. Financing collapsed mid-production; cast and crew were paid intermittently; the shoot dragged on for three years across Italy, Morocco, and wherever funds materialised. What emerged was a masterpiece of improvisation.
El Jadida’s cistern appears as a Venetian dungeon in the film’s climax. The low vaulting, the water underfoot, the light filtering through the single overhead aperture — Welles apparently visited the space once, said little, and immediately began planning the scene. The footage shot here has a quality of dread and stillness that served Shakespeare’s text better than any studio set would have.
A plaque inside the cistern commemorates the shoot. If you go in without knowing the film’s history it is still spectacular. If you watch the movie beforehand — even just the 10-minute sequence available online — walking into the space becomes something else entirely.
Mazagan: The UNESCO Walled City Around It
The cistern cannot be understood in isolation from the walled city that contains it. Portugal established Mazagan in 1502 as a trading post and military base on the Atlantic coast. Over the following two centuries they built one of the best-preserved examples of Renaissance military architecture outside Europe — a diamond-shaped fortification with four bastions and sea walls thick enough to double as promenades.
When Sultan Mohammed III laid siege in 1769, the Portuguese garrison blew up part of the fortifications and evacuated by sea to Brazil, taking many of the city’s Jewish residents with them. Moroccan families moved in; the city was renamed El Jadida ("the new one"); and the Portuguese buildings were gradually absorbed into daily life. The cistern became a market — a butcher’s stall operated inside it for decades — before archaeological interest in the 20th century led to its preservation.
UNESCO inscribed the Cité Portugaise in 2004. The designation covers the full fortification — walls, bastions, the Church of the Assumption (still a functioning space, now used for exhibitions), and the cistern. Walking the rampart circuit takes about 25 minutes and the views over the Atlantic justify the effort even if you have no interest in colonial history.
Getting to El Jadida
El Jadida sits on the Atlantic coast, equidistant from Casablanca to the north and Marrakech to the south-east. It is reachable as a day trip from either city.
| From | Distance | Options | Recommended |
|---|---|---|---|
| Casablanca | ~100 km | CTM/Supratours bus from Ouled Ziane (1.5 hrs, from ~30 MAD) or grand taxi (~80 MAD shared, 1.5 hrs). Train to Settat then onward bus is slower. | Bus or grand taxi |
| Marrakech | ~200 km | Grand taxi or private car via the A7 motorway (~2.5 hrs). No direct bus; change in Casablanca or take a private day-trip. | Private car / day trip |
| Essaouira | ~175 km north | Best done by private vehicle — about 2 hrs along the N1 coast road, passing Safi. | Private car |
Private driver costs are indicative; expect to pay from around 600–900 MAD from Casablanca for a return day trip, more from Marrakech given the distance. A guided private tour from Marrakech typically combines El Jadida with Azemmour, another Portuguese-era walled town 16 km north.
What Else to See in El Jadida
The cistern alone takes 20–40 minutes; combine it with these stops for a satisfying half-day or full-day visit.
Cité Portugaise ramparts
Walk the 16th-century sea walls encircling the medina; the views over the Atlantic are worth 30 minutes.
Church of the Assumption (Igreja da Assunção)
Manueline Gothic church inside the Portuguese walled city, now used for art exhibitions.
El Jadida old medina fish market
Just outside the Portuguese walls, fresh Atlantic catch grilled on the spot from early morning.
Moulay Abdallah beach
Wide sandy crescent 4 km south of El Jadida — good for a swim before the drive back.
Portuguese Cistern El Jadida — FAQs
What is the Portuguese Cistern in El Jadida?
The Portuguese Cistern (La Citerne Portugaise) is a 16th-century underground water reservoir built inside the walled Portuguese colony of Mazagan — today the old medina of El Jadida. It sits beneath the city at street level, and a shallow film of water that has accumulated over centuries now covers the floor, turning its five Gothic-arched aisles and vaulted ceiling into a mirror-image reflection. The effect — columns rising into reflected columns — is genuinely startling and unlike anything else in Morocco. The cistern is roughly 35 metres long by 25 metres wide, supported by 25 pillars arranged in a five-by-five grid, with a single skylight cut through the vault overhead.
Was Orson Welles’ Othello filmed in El Jadida?
Yes. Orson Welles shot key scenes for his 1952 adaptation of Othello — which won the Palme d'Or at Cannes — in El Jadida, including the famous cistern sequence. Budget problems plagued the shoot and forced Welles to be creative with locations; the cistern's cathedral-like resonance and natural drama made it ideal as a Venetian dungeon stand-in. A small plaque inside the cistern acknowledges the filming. Film-tourism interest has grown since the movie was restored and re-released in the 1990s, and Welles aficionados now make El Jadida a pilgrimage stop on a wider Morocco trip.
How do you get to El Jadida from Marrakech or Casablanca?
From Casablanca, the easiest route is the CTM or Supratours bus from the Ouled Ziane station (roughly 1.5 hours, from around 30–40 MAD indicative). Shared grand taxis from near the bus station take a similar time for around 80 MAD per seat. From Marrakech, El Jadida is roughly 200 km away — about 2.5 hours by private car via the A7 motorway. There is no direct bus from Marrakech; you would change in Casablanca. The most comfortable option from either city is a private guided day trip, which adds local context and handles all the logistics.
Is El Jadida a UNESCO World Heritage Site?
Yes. The Cité Portugaise (Portuguese City) of El Jadida — including the cistern, the ramparts, the Church of the Assumption, and the walled medina — was inscribed on the UNESCO World Heritage List in 2004 under the name "Mazagan (El Jadida)". It is recognised as an outstanding example of Portuguese Renaissance military architecture and of the cultural exchange between European and Moroccan traditions. The designation covers the complete fortified city and its surviving Portuguese structures, not just the cistern.
What else is there to see in El Jadida besides the cistern?
Plenty. Walk the sea walls of the Cité Portugaise for Atlantic views and old cannon emplacements; the walk takes about 20–30 minutes. The Church of the Assumption inside the walls now hosts temporary art exhibitions. The lively fish market just outside the Portuguese gate — where local fishermen sell the morning catch and grill it on the spot — is worth a stop. Moulay Abdallah beach, 4 km south, is a wide, calm crescent for swimming. Sidi Bouzid beach to the north is popular with Casablancans at weekends. El Jadida is realistically a half-day to full-day excursion.
How much does it cost to enter the El Jadida cistern?
Entrance is inexpensive — around 10 MAD per person (indicative; roughly €1 / $1), making it one of the most affordable heritage sites in Morocco. It is advisable to carry small change, as ticket sellers rarely have change for large notes. Hours are roughly 09:00–18:00 but can vary, particularly during public holidays and Ramadan — always confirm locally or with your guide on the day. There is no extra charge for photography.
When is the best time to visit the Portuguese Cistern for photography?
The cistern has a single ocular skylight cut into the vault, and the reflected light is most dramatic in mid-morning when the sun is at the right angle to send a shaft directly down through the opening, illuminating the columns and their reflections. Visiting between about 09:30 and 11:30 gives the best chance of catching this effect. Midday can work in summer when the sun is high. Avoid the rush of tour groups, which typically arrive late morning — getting there at opening time gives you the near-silent, mirror-still atmosphere that made Welles choose the location.
