Hanover

Pennsylvania, United States
Also known as: McAllister’s Folly, Rogue’s Harbour, Rogue’s Rest(Show More)

Hanover, borough (town), York county, southern Pennsylvania, U.S. It lies in the Conewago Creek valley, 20 miles (32 km) southwest of York. Laid out in 1763 by Colonel Richard McAllister, it was incorporated as a borough in 1815 and named for Hanover, Germany. Earlier it had been known as McAllistertown. Later it was called Rogue’s Roost, and Rogue’s Harbour, because of its lack of law enforcement over boundary disputes between Pennsylvania and Maryland. The first American Civil War battle north of the Mason-Dixon Line was fought there on June 30, 1863, when General J.E.B. Stuart’s Confederate cavalry clashed with Union forces under General Hugh J. Kilpatrick and General George A. Custer.

A trading point for rich farmlands, the borough also has light manufactures (shoes, machine tools, snack foods, and furniture). Nearby Hanover Shoe Farms breeds Standardbred horses. The nearby Conewago Chapel, established as a Jesuit mission and originally built of logs in 1741, was rebuilt of stone in 1787 and designated a Sacred Heart Basilica in 1962. Pop. (2000) 14,535; York-Hanover Metro Area, 381,751; (2010) 15,289; York-Hanover Metro Area, 434,972.
