Rufus Castle

Rufus Castle, also known as Bow and Arrow Castle, is a ruined blockhouse overlooking Church Ope Cove on Portland, England. The castle dates from the late 15th century, possibly on the site of an earlier building (with origins dating from 1142) - making it Portland's oldest castle. Built on a pinnacle of rock, much of the original structure has been lost to erosion and collapse over the years.

The remaining castle appears to have been the keep of a stronghold, the foundation of which was much above the top of the church tower of St. Andrews which lay in the valley below. The pentagonal tower of the castle has late Medieval gunholes, but rests uncomfortably on an earlier foundation to the north and stepped plinth to the west which may have been a 12th-century keep. Remains include parts of the keep, sections of wall with gun ports and a 19th-century round-arched bridge across Church Ope Road.

The castle, including its bridge, has been a Grade I listed building since January 1951. It is one of three buildings on Portland to be Grade I Listed. In addition to this, the castle has become a scheduled monument under the Ancient Monuments and Archaeological Areas Act 1979.
