On the western side of Yacoub al-Mansour's Almohad wall, on what is now the big Place Kennedy roundabout near the Royal Palace district, stands Bab Rouah — the Gate of the Winds. It is the twin of Bab Oudaia in date and dynasty but cleaner and more geometric in feeling: two concentric horseshoe arches set into pink sandstone, stylised carved medallions at the spandrels, and the kind of restraint that reads in textbooks as classic late-12th-century Almohad design.

Walk inside through the bent entrance — the same dog-leg defensive trick the Almohads used on every monumental gate — and the interior opens into three vaulted chambers above the passage. Since the 1980s those chambers have served as an exhibition space run by the Ministry of Culture, with rotating six-to-ten-week shows of contemporary Moroccan painting, photography and sculpture installed under centuries-old stonework. The contrast between the canvases and the carved pisé is one of the more interesting curatorial conversations in the city.

Entry is free during exhibition runs, the most reliable times to see the interior. When no show is up, the upper chambers close and the gate becomes an exterior stop only — still worth approaching for the facade's rhythm of interlocking arches, but a shorter visit. The Ministry posts a banner on the facade announcing each new show, and notices appear around the Ville Nouvelle the week before openings. Pair the visit with a wall walk south toward Bab Zaer and Chellah, or north toward Bab el Had and the medina.
