1. Bahia Palace
What is it? This 150-room palace was home to slave-turned-vizier Abu ‘Bou’ Ahmed, who spared no expense in its gorgeous decoration. The painted, gilded ceilings, polychrome zellige tiling and carved stucco still have the intended effect. That'll be "wow", just so you know.
Why go? Bahia is roughly translated as ‘beautiful’, and that’s definitely not an overstatement. Escape from the heat of the midday sun to the palace’s shaded spaces and get lost in all the intricate detailing.
