This elegant and tasteful mosque dates from 1978 and is the largest in Southeast Asia. Once you have removed your shoes, walk down the marble passageways above the prayer hall, a vast area flooded with light that accommodates 20,000 worshippers every Friday, and which can hold, terraces included, 200,000 pilgrims during major festivals. Twelve aluminium-plated columns endow the structure with a head-spinning sensation of verticality.
