Begun in Karim Khan’s time, this mosque next to the tribal arts arcade in the Bazar-e Vakil has an impressive tiled portal, a recessed entrance decorated with Shirazi rose-pink tiles, two vast iwans, a magnificent inner courtyard surrounded by beautifully tiled alcoves and porches, and a pleasingly proportioned 75m-by-36m vaulted prayer hall. The distinguishing feature of the mosque, however, is the forest of 48 diagonally fluted columns that support the prayer hall, displaying a hypnotic rhythm of verticals and arabesques.
Other fine features include an impressive mihrab and 14-step marble minbar, carved from a monolith transported all the way from Azerbaijan. Much of the tiling, with its predominantly floral motifs, was added in the early Qajar era.
