Mother Mosque of America
Cedar Rapids, United States
The Mother Mosque of America, once known as The Rose of Fraternity Lodge, in Cedar Rapids, Iowa, United States, is considered the oldest still-standing purpose-built mosque in the United States, having been completed in 1934. The Al-Sadiq Mosque in Chicago and the Powers Street Mosque in New York City, founded in 1922 and 1931, respectively, but were converted from existing buildings to be used as a Muslim house of worship. An older purpose-built mosque is the Highland Park Mosque, built in 1921 to serve immigrant workers in the Detroit Metro Area, which was sold in 1926. Another older purpose-built mosque was a mosque near Ross, North Dakota, built in 1929, which fell into ruin; a smaller mosque was built near that site to commemorate its history in 2005.
