Beautiful semi-circular mortar plasterworks are seen around the neck of the dome. A short, narrow and small door forms the entrance of the shrine, with the Pir Shrine lying below the ground surface. This shows that the building was likely to be the temple of Mithraism and the place of worship for the god of Mehr or Mithra prior to the Seljuq dynasty and before Pir was buried there. (Future excavations are likely to prove this.)
Tem-e Sonnati is in fact the name the Spaniards have used for Boghe Pir; it is perhaps a variation of Tomb Saint.
