Visit Threave Castle

Watch a forbidding island fortress come into view as you cross the River Dee by boat. Built by Archibald ‘the Grim’ in 1369 as a stronghold for the Black Douglases, the massive tower house stands 30m tall.

For 21 years the castle was the seat of the powerful Margaret, Lady of Galloway. It is now an ideal spot for exploring, picnicking and, perhaps, painting. The island is rich with wild flowers in summer; you might also see ospreys and otters hunting in the river. To access the island stronghold, take a short boat ride across the River Dee. Stand in awe of the massive tower home — it’s the same height as a 10-storey block of flats! Get up up and personal with the artillery structure that kept James II’s men from infiltrating. While visiting, you can also take the castle fun fact-finding quiz!
