The document provides information about the Masjid-i Imam mosque, formerly known as the Masjid-i-Shah mosque, located in Isfahan, Iran. It was commissioned by Shah Abbas I of the Safavid dynasty in the early 17th century. The mosque is situated in Naghsh-e Jahan Square and was designed to be directly opposite the main entrance of the square. It took several years to complete, finishing in 1630 under Abbas I's successor Shah Safi. The mosque was built with elaborate art, painting, and marble decorations reflective of Safavid wealth and prominence. Today it continues to be an important historical and religious site that also benefits the local economy through tourism.
