Most notable for its Art Deco architecture, the square has become a recognizable icon of the city of Beirut worldwide.

The square was developed in the 1920s when the French decided to destroy the old souks and open streets and transformed it into a modern district.

Its location is believed to be directly adjacent to the site of the ancient Roman law school of Beirut.

Advised to build in the spirit of Lebanese tradition, the architect visited the Emirs' palaces in the Chouf Mountains.

The limestone façade, decorated with recessed panels, arched openings, and tiers of stalactites, clads a reinforced concrete frame that also supports the 20-meter (66 ft) diameter cupola covering the Chamber of Deputies.
