The accessible hill fort, at 160 metres (520 ft) ordnance datum,[2] gives panoramic views across North and Mid Wales, Cheshire and Shropshire.

Entrances were placed at the east and west ends of the earthworks where the inner bank was pulled inwards to create large gateways.

The western entrance was re-modeled with unusual rectangular hollows separated by ridges dug out and defended by outworks.

[6] During the First World War, units of the Canadian Expeditionary Force stationed at nearby Park Hall camp used the earthworks for training purposes.

[1] The war poet Wilfred Owen, who was born in Oswestry, completed his trench warfare training at the hill fort when he was stationed at Park Hall.

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.
