The Curve at Caerlaverock Estate

Caerlaverock is a moated castle on the southern coast of Scotland, about seven miles south of Dumfries. Its triangular shape is unique among British castles, and it has a wide moat, a twin-towered gatehouse and lofty battlements. First built in the 13th century, it was the stronghold of the Maxwell family and was besieged by the English during the Wars of Scottish Independence.

Tip: Head up to the South range for the best views over the moat, then follow the short nature trail to the older castle's foundations.

Sweetheart Abbey is a Cistercian monastery founded in 1273 in the village of New Abbey, about 8 miles south of Dumfries. Dervorguilla of Galloway founded it in memory of her husband, John de Balliol. She kept his embalmed heart in an ivory and silver casket for the rest of her life, and it was buried alongside her. She named the abbey Dulce Cor, Latin for Sweet Heart.

Annandale Distillery in Annan, Dumfries and Galloway, makes single malt Scotch whisky and describes itself as Scotland's only single cask single malt distillery. Every cask is bottled on its own, never vatted. The distillery was founded in 1836, closed in 1924 and was restored after 2007, and it now sits beside a visitor centre.

Tip: Finish your visit with a stop at the Maltings Coffee Shop.

Carlisle Castle guarded the western end of the Anglo-Scottish border for hundreds of years and survived seven sieges by the Scots between 1174 and 1461. It was later adapted for artillery, and in 1568 it held Mary Queen of Scots prisoner. It stayed in military use well into the 20th century.

Drumlanrig Castle is the Dumfriesshire home of the Duke of Buccleuch and Queensberry, set on the Queensberry Estate in Dumfries and Galloway. Built between 1679 and 1689 from distinctive pink sandstone, the "Pink Palace" overlooks the Nith Valley and has 120 rooms, 17 turrets and four towers.

Threave Castle stands on an island in the River Dee, about 2.5 kilometres west of Castle Douglas. Archibald the Grim built it in the 1370s, and it was a stronghold of the Black Douglases, Earls of Douglas and Lords of Galloway, until their fall in 1455.

Cardoness Castle is a well-preserved six-storey tower house just south west of Gatehouse of Fleet, built in the later 1400s for the McCulloch family, a prominent Galloway clan. It is now cared for by Historic Environment Scotland.

MacLellan's Castle stands in the centre of Kirkcudbright, on the south side of the River Dee. Building began around 1577 for Thomas MacLellan, on the site of a ruined Greyfriars monastery. The castle was never finished, and the roof had collapsed by the time the family sold it in 1752. It is now in the care of Historic Environment Scotland.

Tip: Look for the peephole behind the great hall fireplace and the carved coats of arms above the entrance.
