On Connecticut Avenue in Washington, D.C., the cornerstone is laid at the first mosque of note in the United States. Intended to serve as a national mosque for all American Muslims, the Islamic Center was built in a traditional Arabic architectural style, complete with a 160-foot minaret from which prayers were to be announced. A colonnade cloister joined the mosque to two wings containing a library, classrooms, a museum, and administrative offices. In the basement of the mosque was an auditorium built to accommodate several hundred people. The Islamic Center’s first director was Dr. Mahmoud Hoballah.
