The Hanover Area Historical Society selectively acquires, preserves, and provides access to historical buildings and sites and to artifacts and archives that have unique historical significance for this area. The Society also undertakes related programs and activities for the educational, recreational, and cultural benefit of the people of the greater Hanover Area.

The Society was founded in 1965 by local citizens interested in protecting and promoting the historical heritage of the greater Hanover area. The Society acquired and restored the Neas House at the corner of W. Chestnut and High Sts. In October 2007, the Society was given the Warehime-Myers Mansion at 305 Baltimore St. The Mansion is regularly open for public tours and rental. The Society also has a late 19th Century house at 105 High St. where it has its office and a small library. The library holds small collections pertaining to the area's history, and is available to the public by appointment.

Tours of the Warehime-Myers Mansion (first and second floor rooms only) are given 10:00 AM - 3:15 PM on Wednesdays and 12 Noon - 3:15 PM Saturdays (or by appointment). No photographs or large bags are permitted.
