The Detroit Masonic Temple is the largest Masonic temple in the world: a 14-storey, neo-Gothic limestone block opened in 1926, containing two theatres, a ballroom, banquet halls, lodges, and rented spaces over 1,037 rooms. The Cathedral Theatre and the Masonic Temple Theatre still host concerts and Broadway shows. The building's surprising public function makes the interior accessible: buy a ticket to a show, take a tour, or just walk into the lobby.
Tours run occasionally by the Masonic group and offer access to ornate rooms not used for public events. The block is in the Cass Corridor, near Wayne State University.
