Morton Castle

Morton Castle is located by an artificial loch in the hills above Nithsdale, in Dumfries and Galloway, south-west Scotland. It lies 2.5 miles north-east of Thornhill, and once formed part of a chain of castles along the strategically important Nith Valley, which runs from the Solway Firth north to the Clyde Valley.

In the 12th century, the honour of Morton was a possession of Dunegal, Lord of Strathnith (Nithsdale). A ditch to the south of the castle is thought to date from this period, although it may be natural. During the reign of Robert the Bruce the lands of Morton were held by Thomas Randolph, later the first Earl of Moray. By 1307, and possibly as early as the 1260s, a castle had been constructed here, on a high defensible promontory surrounded by marshland. Randolph also constructed an enclosed deer park nearby.

The Treaty of Berwick in 1357, which secured the release of David II, also required the Scots to destroy thirteen castles in Nithsdale, including Morton. It is not clear how much, if any, of the original castle remains.

The lands of Morton passed to the earls of March, who probably built (or rebuilt) the existing castle in the early 15th century.

In the mid 15th century the lands were given by James II of Scotland to James Douglas of Dalkeith, later Earl of Morton (although the earldom is named for another Morton in Lothian).

The fourth earl of Morton was executed in 1580 for his alleged part in the murder of Lord Darnley, and Morton Castle, together with the earldom, briefly passed to John Maxwell, 7th Lord Maxwell, and grandson of the third earl. However, in 1588, James VI led an expedition against the Catholic Maxwells. Morton Castle was taken and burned, and returned to the Earls of Morton, the fourth earl's attainder having been reversed.
