The Arab Fort (Old Fort) is situated next to the House of Wonders and was built between 1698 and 1701 by the Busaidi group of Omani Arabs. It is a large building with high, dark brown walls topped by castellated battlements. The Arabs used the fort to defend themselves against the Portuguese and against a rival Omani group. In recent years it has been partially renovated to house the Zanzibar Cultural Centre. In an inner courtyard lies a stone-built amphitheatre that hosts performances of local music and dance, such as Taarab, Zanzibar’s most popular form of music. There is a small tourist information office, a gift shop and art gallery and the very pleasant Neem Tree Café.
