Résumé en anglais
Zanzibar has a rich history, having been the cosmopolitan focus of Arab, African, Indian and European influemce on the East African coast. The Stone Town, mainly built in the 19th century during a boom of trade with spices, ivory and slaves represents many individual historical buildings but also an undisturbed historical environment as a whole. It has survived until today, despite of changes. Zanzibar's period as a British Protectorate brought a good administration and infrastructure to Stone Town, but stagnation and decline of trade already affected the development of the town.
