Old Oswestry

Old Oswestry is a large early Iron Age hill fort in the Welsh Marches near Oswestry in north west Shropshire, England [1]. The earthworks remain one of the best preserved hill forts in the UK and have been described as "The Stonehenge of the Iron Age Period" [1]. After the hill fort was abandoned, it was incorporated into Wat's Dyke by the Mercians during the Early Medieval period [1].
