Caerlaverock Castle
13th century fortress surrounded by moat and was built by Sir Herbert Maxwell. It is one of the few castles in Scotland with a protective moat. It has been attacked many times, in 1300 a garrison of 3000 troops of Edward I of England laying siege to it; the sixty men inside held out for two days. It was attacked and destroyed on at least five other occasions and, with the exception of the final attack, it was always rebuilt
