Built during the Safavid period between 1611 to 1629 by architect Shaykh Baha, the Imam Mosque of Isfahan it is an excellent example of Islamic architecture of Iran, and regarded as one of the masterpieces of Persian Architecture.  It is registered, along with the Naghsh-i Jahan Square, as a UNESCO World Heritage Site. Although the Imam mosque is massive and initially impressive, in my view the neighbouring Sheikh Lotf Allah Mosque and the Jameh Mosque of Isfahan are of greater scuptural subtlety and sublime geometrical beauty.
