The Castine Historic District encompasses the entire southern tip of the peninsula on which the town of Castine, Maine is located. Covering about 1,800 acres (730 ha), this area was a center of colonial conflicts dating to the early 17th century, and was the site of military action during the American Revolutionary War and the War of 1812. Bypassed by the railroads, it has retained a village feel reminiscent of the early 19th century. It was listed on the National Register of Historic Places in 1973.
