The construction of the Zagreb Mosque and Islamic Center in Trstik began in 1981 and was finished in 1987. Sarajevo-based architects Dzemal Celic and Mirza Golos built a complex of around 10,000 square meters. It consists of several functional units: a place of worship with a minaret (51 m high), and Islamic religious high school (a medresa), a library, common social premises, administration building, residential parts and other facilities. Though its interior and exterior preserve the traditional patterns and contents the architecture of the complex is in harmony with the modern construction trends. It is regarded as one of the most beautiful mosques in Europe by many.
