A smaller domed shrine immediately adjacent to Shah Cheragh, dedicated to Seyyed Mir Mohammed, another brother of Imam Reza. The main hall is mirrored in the same style as Shah Cheragh, and the two complexes share a single courtyard — visiting one effectively brings you to the other.
This is a quieter place than its famous neighbour, and a useful refuge if Shah Cheragh's crowds feel overwhelming. Local women in chadors sit on the carpets in long stretches; the atmosphere is calm and unhurried.
