The Detroit Masonic Temple is the world’s largest Masonic Temple. Located in the Cass Corridor of Detroit, Michigan, at 500 Temple Street, the building serves as a home to various masonic organizations including the York Rite Sovereign College of North America. Detroit’s Masonic Temple (“The Masonic”) is the largest building of its kind in the world. Construction began in 1920 and was completed in 1926. Land on Bagg Street (now Temple Avenue) was acquired and by 1920, the architectural firm George Mason and Company had completed an integrated design of a multi-function complex. Ground was broken on Thanksgiving Day, 1920. The cornerstone was laid on September 18, 1922, during a ceremony attended by thousands of Detroiters, using a trowel previously used by George Washington during the construction of the U.S. Capitol.
