Eighty-two domes, a courtyard paved in floral marble inlay, and the largest hand-knotted carpet in the world in the main prayer hall. Entry is free, and the dress code is enforced rather than suggested: ankles and shoulders covered for everyone, hair covered for women, and abayas are lent at the entrance to anyone who arrives without. Go towards dusk — the lighting scheme shifts with the phase of the moon, and the building is at its best as it comes on.
