Threave Castle

Threave Castle is a stone tower rising about 21 meters above an island in the River Dee in Dumfries and Galloway. The structure has thick walls and medieval fortifications, including a separate artillery building with gun ports for defense.

Archibald Douglas, the third Earl of Douglas, had the castle built in 1369 to create a main stronghold for the Black Douglas clan. In the 15th century, the artillery section was added to defend against forces sent by James II.

The name comes from the ancient Cumbric word 'tref', showing that early settlements existed here before Gaelic speakers arrived in the area. This linguistic link reveals the layered past of the region before the feudal period took hold.

A small boat service takes visitors from the mainland to the island during opening hours from April to September. Wear sturdy shoes and be prepared for uneven ground when exploring the ruins.

The site lay abandoned for a long time and is now partially overgrown, giving it a quiet, forsaken appearance. This seclusion makes the journey to the island feel like a peaceful experience quite different from more visited castles.
