Overview

History & significance

Roundton Hillfort is a prehistoric fortified settlement located in Montgomeryshire, Wales, dating to the Iron Age. The site is defined by a substantial univallate earthwork comprising a single defensive bank and ditch enclosing an irregular hilltop position. Archaeological evidence and structural characteristics suggest occupation and defensive function during the later prehistoric period, typical of hillforts constructed across Wales and the Marches during the Iron Age millennia. The monument remains a significant example of prehistoric settlement hierarchy and territorial organisation in the region.
