Mirror Mosque, Shiraz, Iran

[Source]

The tombs became celebrated pilgrimage centres in the 14th century when Queen Tashi Khatun erected a mosque and theological school in the vicinity. The decorative work in a mosaic of mirror glass, the inscriptions in stucco, the ornamentation, the doors covered with panels of silver, the portico, and the wide courtyard are most attractive. The tomb, with its latticed railing, is in an alcove between the space beneath the dome and the mosque. [Wiki]
