The St. Augustine Free Public Library is the oldest non operating library in Florida; opened in 1874 as a "subscription library." The library was first located in the U.S. Customs house, now known as the Government House at 48 King St, St. Augustine, FL. Its second location, at 12 Aviles Street in St. Augustine, Florida, is the building currently known as the Segui-Kirby Smith House and still stands as a Research Library for the Saint Augustine Historical Society.
