Larache's kasbah is not polished, but its worn walls and Atlantic views make it worth folding into a walk through the old town. The fortifications are usually linked to the Portuguese period, later absorbed into the town's Moroccan and Spanish layers.
Come for the setting rather than museum-style interpretation. The stonework is crumbling in places, the signage is thin, and that roughness is part of the appeal: Larache still feels lived-in rather than staged for visitors.
