Heritage in Muscat

Opened in 2001, with a vast Persian-style carpet, a Swarovski chandelier and fine tilework. Non-Muslim visitors are welcome Saturday to Thursday mornings until 11:00, not Fridays; cover arms and legs, and women cover their hair.

The 17th-century round tower of the Ya’ariba imams, beside Nizwa’s old mosque and souq, once a centre of Ibadi scholarship. Go on a Friday morning for the livestock market; check fort hours before you go.
