The Sultan Salahuddin Abdul Aziz Shah Mosque, also known as the "Blue Mosque" in Shah Alam is heralded as one of the largest mosques in Southeast Asia and the most stunning structures in the country. Its most distinguishing feature is its large blue-and-white dome, measuring 52m in diameter and reaching 107m from the ground up.

The mosque has four minarets, measuring 140m high, the tallest minarets in the world. Decorative Islamic calligraphy dominates the edges surrounding the dome and main prayer hall, while the interior architecture exhibits ethnic Malay design elements. Sunlight filtering through the blue stained glass of the mosque renders a bluish ambience to its interior, evoking a sense of peace and serenity.

The Blue Mosque overlooks the Garden of Islamic Arts, a beautifully landscaped park inspired by the Quranic Garden of Paradise. Covering 14 hectares, this spiritual sanctuary houses nine galleries that exhibit a rich array of Islamic arts such as calligraphy, sculptures, paintings and architecture. Occasionally, traditional Islamic performances are held here. The mosque can accommodate up to 24,000 worshippers at a time.
