The name Ali Qapu, from Persian ‘Ālī (meaning "imperial" or "great"), and Azerbaijani Qāpū (meaning "gate"), was given to this place as it was right at the entrance to the Safavid palaces which stretched from the Naqsh e Jahan Square to the Chahar Baq Boulevard. The building, another wonderful Safavid edifice, was built by decree of Shah Abbas I in the early seventeenth century. It was here that the great monarch used to entertain noble visitors, and foreign ambassadors. Shah Abbas, here for the first time, celebrated the Nowruz (Iranian New Year)
