Crucial to the development of a vibrant Islamic architecture is the design of mosques expressive of the changing realities of Muslim life. Modeled on the layout of the Prophet's own home, the mosque has shaped Muslim society from its beginnings. In addition to being the place where the community worshiped on Friday nights, it was where civic meetings were held, legal cases argued, the treasury kept. Despite its many worldly functions, the mosque has always remained a profoundly sacred place; one removes one's shoes upon entering it. A 1980 work by architect Zlatko Ugljen, this mosque was honored by the AKAA in 1983. One of the early standouts of the award, it gracefully weaves traditional Islamic elements and folksy details into Corbusian forms and plays of light. This inspired mix of the sophisticated and the earthy epitomized what was once the promise of Bosnia-Herzegovina's mosaic culture.
