Sultan Salahuddin Abdul Aziz Mosque, State mosque in Shah Alam, Malaysia.

The Sultan Salahuddin Abdul Aziz Shah Mosque is the state mosque of Selangor, standing in Shah Alam on rising ground north of the Shah Alam lake. Its blue and silver dome, 51.2 m across and 106.7 m high, is clad in vitreous enamel-baked steel panels with Qur'anic verses; four banded minarets rise 142.3 m at the corners. The two-level prayer hall holds 12,600 worshippers.

Sultan Salahuddin Abdul Aziz ordered the mosque built after declaring Shah Alam the capital of Selangor on 14 February 1974. Construction began in 1982 and the mosque opened on 11 March 1988, with the Sultan himself officiating. The design by Jurubina Bertiga Arkitek, led by Dato' Baharuddin Abu Kassim, followed research visits to several Islamic countries.

Locals call it the Blue Mosque after its blue and silver dome. The state mosque doubles as a venue for Islamic arts: it overlooks the 14-hectare Garden of Islamic Arts, whose nine galleries show calligraphy, sculpture and painting, and which occasionally hosts traditional Islamic performances.

Visitors should wear modest clothing that covers shoulders and knees, and women receive a robe at the entrance. The expansive grounds require some walking, so comfortable shoes are recommended, as you remove footwear before entering prayer areas.

The dome ranks among the largest of its kind worldwide and uses blue and silver aluminum panels that shift color depending on sunlight. Egyptian craftsmen were specially commissioned to create the ornate Quranic verses on the interior walls using traditional calligraphy.
