Malaysia's Masjid Negara is one of the largest mosques in Southeast Asia and is the spiritual centre for Malaysia's Muslims. Built on 5 landscaped hectares (12 acres) behind the railway station, the mosque consists of a grand prayer hall, mausoleum, library, and offices opening onto a courtyard. It has a 75-metre (245-foot) minaret. The roof is an umbrella-shaped dome with 18 points representing the 13 states of Malaysia and the Five Pillars of Islam.
