The Mausoleum of Sheikh Safi, in Ardabil, was first built by his son Sheikh Sadr al-Dīn Mūsā, after Sheikh Safi’s death in 1334. It was constructed between the beginning of the 16th century and the end of the 18th century.

It incorporates a route to reach the shrine of the sheikh divided into seven segments, which mirror the seven stages of Sufi mysticism. Various parts of the mausoleum are separated by eight gates, which represent the eight attitudes of Sufism.
