Tangier's 17th-century fortified residential quarter, or Kasbah, is a place of arcades, winding alleys and hidden terraces, where it is possible to wander among the wealthy homes and sometimes manage a peep behind the unprepossessing facades, enjoying views of the medina and the bay. The Kasbah mosque features an interesting octagonal minaret, and stands in the mechovar (parade ground). Visitors are welcomed at the Sultan's Gardens in the Rue Riad Sultan to the north of the mechovar, where they can watch local craftsmen at work and sit awhile on the terrace of the Moorish café Le Detroit. On a clear day it is possible to see the Spanish city of Tarifa about 18 miles (30km) away. There are food and craft stalls in the Kasbah, which seems always to smell of spices. Look out for fresh seafood if you're hungry, and handmade carpets to buy as souvenirs. The Kasbah is one of the most picturesque areas of the city; it looks how foreigners expect a Moroccan city to look and photographic opportunities abound. Numerous tours of the district are available, but it is actually more fun to wander the little alleys alone and really soak up the atmosphere at your own leisure.
