The Sheikh Safi al-Din Khanegah and Shrine Ensemble in Ardabil is a Sufi spiritual retreat dating from between the early 16th century and late 18th century. It is the burial site of Safi al-Din Ardabili (B. 1252/3), the eponymous founder of the Safawiyya order of Sufism. The complex is a fine example of medieval Iranian architecture.
The shrine was an important site of pilgrimage throughout the Safavid period (1501-1722) and underwent numerous improvements and embellishments to become one of the most beautiful of all Safavid monuments.
The site includes a library, a mosque, a school, a mausoleum, a cistern, a hospital, kitchens, a bakery and some offices. The floor of the shrine is covered with a reproduction of the most famous carpet in the world – the Ardebil Carpet.
