The Zagreb Mosque, located in the city of Zagreb, is the largest mosque in Croatia. The Islamic Secondary School "Dr. Ahmed Smajlović" and a cultural centre operate within the mosque. The construction began in 1981 and finished in 1987. The construction of the Islamic Centre of Zagreb 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 modern construction trends.
