This awe-inspiring white mosque, built between 1922 and 1926, has tranquil arcades and a minaret decorated in the style of Moorish Spain. Enjoy sweet mint tea and an exotic pastry in the charming courtyard tea salon or tuck into some couscous in the restaurant. Prayer rooms are not open to the public. But there are inexpensive—and quite rustic—hammams, or Turkish steam baths, with scrubs and massages on offer (women only; check website for prices).
