Green Island is an Iron Age fort located on a rocky promontory within Milton Loch near Kirkcudbright in Dumfries and Galloway. The fort occupies a naturally defensible position, its isolation by water providing substantial protection to its inhabitants. The underlying bedrock comprises Hawick Group wacke, a hard sedimentary rock formed during the Wenlock epoch, which would have offered a stable foundation for settlement.
The fort exemplifies the crannóg tradition of Iron Age fortification in south-western Scotland, where communities constructed defended settlements on islands and peninsulas. This defensive strategy, combined with the rock's natural topography, created a formidable stronghold. The loch setting would have enabled control of local water routes and facilitated trade across the region's interconnected waterways, essential to Iron Age economies.
The monument is protected by Historic Environment Scotland as a scheduled ancient monument under reference SM1074, reflecting its archaeological significance. Green Island remains an important example of Iron Age settlement patterns in the south-west of Scotland, demonstrating how communities strategically exploited their landscape to create secure, strategically positioned fortifications during this period.
