Diyanet Center of America is a non-profit organization funded by the Turkish government that is based in Lanham, Maryland, serving the needs of the Muslim community in the Washington Metropolitan Area. The center holds regular Friday congregational prayers, Ramadan dinners, religious holiday celebrations – including Mawlid – and various other social, cultural, and religious activities.The center benefits from its proximity to the nation's capital, various federal and state institutions, and schools.
The complex consists of five main buildings, an underground parking garage, and a geothermal well field on a 15-acre site. The five buildings are a mosque constructed using 16th century classical Ottoman architecture, a cultural center building, a guest house, a fellowship hall with a restaurant and shops, and a recreational building housing a Turkish bath, an indoor pool, and a sports center.
