Dinnans is a pair of Iron Age forts located in Wigtownshire in south-west Scotland. The two fortifications occupy a commanding position on bedrock of the Hawick Group, a formation of hard wacke stone laid down during the Wenlock period of the Silurian era. This naturally resistant geology provided an excellent foundation for defensive structures and would have offered the inhabitants stone suitable for construction. The site benefits from protection as a scheduled monument under Historic Environment Scotland's designation SM1968.
The twin-fort arrangement at Dinnans reflects a settlement pattern common to Iron Age communities in south-west Scotland, where multiple fortified enclosures often functioned as related settlement units. Such forts typically enclosed domestic and stock-management areas behind substantial timber-laced ramparts or stone walls. The Wigtownshire location places Dinnans within a region that shows evidence of sustained Iron Age occupation and trade networks extending across the Irish Sea and into northern Britain.
The surviving earthworks and stone remains at Dinnans contribute to understanding Iron Age settlement hierarchies and land use in the south-west Scottish uplands during the pre-Roman Iron Age. The site's elevated position and dual-fort layout suggest both practical defensive advantages and possible social significance within the landscape of ancient Wigtownshire.
