The Shah Cheragh — "King of Light" — is the mausoleum of Sayyid Ahmad, brother of the eighth Shia Imam, and one of the most important pilgrimage sites in Iran. The 12th-century complex sits in the heart of the old city near the bazaar, with a vast inner courtyard and twin minarets rising above the surrounding rooftops.
The mirrored interior is the reason most travellers come. Every surface above shoulder height is faced in millions of small mirror fragments, and the chandeliers, gilded tiles, and silver grilles around the tomb create one of the most dramatic religious interiors you will see anywhere. Visit in the evening when the lights are on and Iranian families gather to pray, picnic on the carpets, and watch the children run between the columns.
A 2022 attack on the shrine left a sombre note on a place that for most of its history has felt warm and welcoming. Visitors are still received, but security at the gates is tighter than it once was.
