The Mohammad Al-Amin mosque is the biggest mosque in Lebanon. The main feature of Mohammad Al-Amin Mosque lies in its location in the commercial center of Beirut where it’s surrounded by several Christian and Islamic religious sites and overlooks Martyrs Square from the east. Architect Azmi Fakhouri was responsible for the architectural planning of the mosque while the interior was designed by Nabil Dada & Associates. The mosque is considered a landmark and a dominant feature of the Beirut skyline. It is estimated to be the largest mosque in Beirut in terms of surface area and number of worshippers and it resembles the Muhammad Ali mosque in Cairo as well as the Blue Mosque in Turkey.

The design of Mohammed Al-Amin Mosque adheres to the Ottoman Turk’s mosque architecture e. It was inaugurated in 2008. The Mosque’s design was inspired by the Sultan Ahmet Mosque in Istanbul. The design contains multiple domes, all of which are dyed in a distinctive blue colour since according to the architect “blue is a landmark on a landmark”. The mosque  has a built area of approximately 11,000 square meters distributed over four floors. In terms of style and expression, it has large, elevated interior spaces coupled with a heightened blue light dome, a perforated pendentive for lighting that rests on two semi-domes, 4 slender minarets placed on the dome’s corners and large multi-story arches. The mosque is clad in what is fondly referred to by Lebanese architects as the Beiruti yellow sandstone in order to integrate it aesthetically with the Beirut City Center, although the stone itself was mined in Riyadh, Saudi Arabia and shipped to Beirut from there, the large central dome is clad in light blue tiles. Also, the mass of the mosque is made up of two interlocking volumes, a four-sided irregular polygon that describes the lot, and in it is a square that defines the orientation to the Qibla. Throughout the interior Turkish tiles of decorative blue color have been used and the walls are covered with desert stone, imported from the Kingdom of Saudi Arabia whereas its domes are coated in colour, ornamented gypsum.
