Port Gibson Battlefield is located in Mississippi

The Port Gibson Battlefield was listed on the National Register of Historic Places in 1972. It is 2,080 acres (840 ha), more than two square miles. A somewhat larger, overlapping area, the Port Gibson Battle Site, was designated a National Historic Landmark and automatically listed on the National Register in 2005. The NRHP site includes some area not covered in the NHL listing (see p. 34 of NHL document). Both areas include the Shaiffer House, which was located in one area of intense fighting in the 1863 battle, and which still stands.
