Oman's main mosque and one of the most impressive Islamic buildings of the modern era. Completed in 2001, it holds up to twenty thousand worshippers and features a single hand-woven Persian carpet — 4,343 square metres, woven in Iran over four years — and a chandelier eight metres tall with more than a thousand lights.
Open to non-Muslim visitors in the morning (usually 8am–11am) except Fridays. Modest dress is required: long trousers for men, a head scarf and full covering for women (scarves can be borrowed at the entrance if needed).
