Old Oswestry () is a large early Iron Age hill fort in the Welsh Marches near Oswestry in north west Shropshire, England. The earthworks, which remain one of the best preserved hill forts in the UK, have been described as "The Stonehenge of the Iron Age Period". After the hill fort was abandoned, it was incorporated into Wat's Dyke by the Mercians during the Early Medieval period. gives panoramic views across North and Mid Wales, Cheshire and Shropshire.

History

The earliest occupation of the site began in the 8th century BC and continued up until the Roman conquest of Britain. Its inhabitants were either from the tribes of the Cornovii or Ordovices.

The complexity of defences suggests there have been several phases of development. In the earliest period, a few round huts were sited on the undefended hillock. Subsequently these were enclosed by a double bank and ditch that enclosed . Entrances were placed at the east and west ends of the earthworks where the inner bank was pulled inwards to create large gateways. Later a third bank was added on all sides except the south east where the hill's steep incline made it unnecessary.

The western entrance was re-modeled with unusual rectangular hollows separated by ridges dug out and defended by outworks. The eastern entrance was also strengthened with two further external circuits of banks and ditches.

During the First World War, units of the Canadian Expeditionary Force stationed at nearby Park Hall camp used the earthworks for training purposes. Many large pits, trenches and craters from explosives irreparably damaged the interior site during these military activities.

Preservation

In 1934, Old Oswestry was listed as a scheduled monument, along with two adjacent sections of Wat's Dyke.

In 1939–40, geologist and amateur archaeologist William J. Varley conducted the most extensive examination of the site. His work, which was not published until the 1990s, remains the most authoritative work on the site. His excavations showed that the complex defensive ramparts that surround the hill fort were not built at the same time and that there were four distinct phases in their development.

The hill fort is managed by English Heritage. Access is free.

Since 2015, housing developers have been trying to get planning permission for new homes near the slopes of the ancient monument. However, an ongoing campaign (backed by local residents and archaeologists) has stalled these proposals.

In 2024 a 3D model was produced to inform vegetation management.
