Clothing must be loose-fitting with long sleeves that cover the wrists. Clothing must cover legs to the ankles and women must take a headscarf to cover their heads. Shoes must be removed before entering the mosque. There is approximately 1½ hours of walking on this tour, over mostly paved surfaces, with 25 steps at the museum.
