Naqshe-e Jahan Square, also known as Imam Square is a historical complex in the heart of ancient Isfahan. The square was constructed by Shah Abbas I at the beginning of 17th century. This square is surrounded by historical monuments on all sides, and all these monuments are linked together by two-story arcades. The monuments that surround the square include Ali Qapu Palace, Shah Mosque, Sheikh Lotfollah Mosque and Qeysarie Gate. At first, there was a vast garden called Naqshe-e Jahan (image of the world) long before Isfahan had become the capital of Persia during Safavid reign. The square was one of the largest squares of the world in 17th century, and Sir John Chardin (a French jeweler and traveler) described it as the most beautiful square in the world. During Shah Abbas the Great and his successors, Naqshe-e Jahan Square was the place for royal celebrations, army parades, and other performances. Beside these, on normal days, the square was a place for shopping. The square was registered as national heritage in 1934 and also, as one of the UNESCO World Heritage sites in May 1978. Many travelers and tourists who described Isfahan in recent times, spoke about the magnitude of Naqshe-e Jahan Square and its important role during Safavid dynasty.
