One of the largest mosques in South-east Asia, this impressive building is frequently referred to as "the blue mosque." It is huge and magnificent with an enormous, dark blue dome and four minarets standing at 142.3 metres. Decorative Islamic calligraphy enhances the dome and main prayer-hall, while the overall architecture integrates ethnic Malay design elements. The mosque is adjoined by a small lake, which makes it a particularly serene setting, especially at sunset.
