Dar el Bahar — the Sea Fortress — stands on the headland at the very edge of the Atlantic, its stone battlements washed by salt spray. Built by the Portuguese in the 16th century, it commands sweeping views south along the coast and north toward the medina. It is one of the best-preserved examples of Portuguese military architecture in Morocco.
Inside, the fortress is compact but interesting: cannons still point out to sea from the wall platforms, and the interior courtyard holds Portuguese inscriptions and carved stonework. The views from the ramparts at sunset are particularly good. Entry is cheap and the site is rarely crowded.
