The main building includes the original 34' square portion built in the 1880's, which was used in 1894 to house the Courthouse records while a new Courthouse (the County's second, and nucleus of the present building)  was being built. The Society acquired the use of half of this nucleus in 1956 to be used as the beginning of a 'home' for the Society's acquisitions. The Pauline Holcombe Wing was added to the original section in 1988 to further expand the facility.
