This beautiful example of Islamic architecture provides a wonderful insight into the cultural heritage of Oman. It is also the only mosque that allows entry for non-Muslims. Apart from being a place of worship, this huge mosque is a centre for scholars and houses an Islamic reference library containing over 20.000 sources of information on Islamic sciences and culture.

The mosque is lavishly decorated, and features a 263m prayer carpet, 35 crystal chandeliers (the central one is 14 meters high and 8 meters wide), and a floor entirely paved with marble. The tour takes you into the men's and women's prayer halls, where you are allowed to take photographs.

There are strict rules governing entry of non-Muslims into the mosque. You must take your shoes off before entering, and both men and women should wear conservative clothing (women should wear long sleeves and long trousers and cover their hair).

Children under 10 years are not permitted inside the mosque.
