With its historic centre, Esfahan is situated on the banks of the Zayandeh Rud River and is a gem of ancient Persia.

In the centre of the historic city centre is the modest Pillar Halls Mosque which is thought to have been built above a fire temple. In around 1087, Seljuk vizier, Nizam Ol-Molk, had the pillar hall and its many small brick domes, completed. Due to a fire lit by the Assassins in 1121 A.D., the original mosque was destroyed.

Following the death of Shah Abbas, around thirty thousand Christian Armenians settled in the Julfa district where they built the Savior Cathedral. Its interior features the history of the Christianisation of Armenia that is depicted on several illustrated panels created by the Holy Gregor.

The grandeur of Islamic architecture is reflected in Emam Square, the central square of the Safavid Era, known as "The image of the world". It is seven times larger than the Piazza San Marco in Venice.

To the south the square is lined by a domed structure which for some years has been known as the Emam Khomeini Mosque, perfectly aligned toward Mecca.

Esfahan is an architectural work of art and today one of the most beautiful cities in the world.
