Peace Arch is unique among parks because it consists of two parks in two countries. The southern half of the park and the monument itself is owned by Washington State Parks and the northern half, by British Columbia Provincial Parks. The 67-foot concrete arch, which is listed on the National Register of Historic Places, was constructed to honor the centennial of the treaties resulting from the War of 1812. These agreements between the U.S. and Britain established a peaceful, undefended border between the U.S. and Canada.
