The Masonic Temple is a historic Masonic building in Philadelphia. Located at 1 North Broad Street, directly across from Philadelphia City Hall, it serves as the headquarters of the Grand Lodge of Pennsylvania, Free and Accepted Masons. The Temple was designed in the medieval Norman style by James H. Windrim, who was 27 years old at the time he won the design competition. The massive granite cornerstone, weighing ten tons, was leveled on St. John the Baptist's Day, June 24, 1868. (wikipedia.org)
