The Old Seminary Building, also known as The Old Masonic Lodge or Lawrencevile Female Seminary Building, is a building in Lawrenceville, Georgia, USA, that was built in 1854 in Greek Revival and Federal style. It was originally constructed as a school but has had various tenants through the years, most notably Lawrenceville Lodge No. 131 Free and Accepted Masons, who used the second story of the building for meetings for more than a century (the lodge now meets elsewhere).
