The Peace Arch is on the Canada–United States border between the Blaine, Washington and Surrey, British Columbia. It is 67 feet tall and dedicated in September 1921, commemorates the signing of the Treaty of Ghent in 1814. The monument is built on the exact United States–Canada boundary, between Interstate 5 and Highway 99, in the grass median between the northbound and southbound lanes. The Peace Arch has the flags of the U.S. and Canada mounted on its crown, and two inscriptions on both sides of its frieze. The inscription on the U.S. side of the Peace Arch reads “Children of a common mother,” and the words on the Canadian side read “Brethren dwelling together in unity”. Within the arch, each side has an iron gate mounted on either side of the border with an inscription above reading “May these gates never be closed.”
