It was built as a motte and bailey castle in the 12th century by Hugh de Hardreshull in 1125. Robert de Hartshill was killed alongside Simon de Montford in the Battle of Evesham in 1265 and the castle fell into disuse. In 1330, it was rebuilt by John de Hardreshull.
In Tudor times a timber framed Manor House was built into the corner. Now all that remains of it is a chimney. The earthworks of the castle and remains of the house are still present. The site is privately owned. In Tudor times before the battle of bosworth, King Henry VII stayed. a war broke out at the castle ruining it to disrepair.
No other place in Warwickshire has such evidence of continuous habitation since earliest times as this Hartshill/Oldbury Ridge.
Stone Age tribes lived here in 10,000 B.C. They were Normads, not traveling far, but wandering, always returning to this area for flints which they needed for tools and weapons. They found them in the boulder clay at the foot of Hartshill Ridge, near the River Anker. Remains of Stone age Flints and bones of Red Deer and Woolly Rhinoceroses have been found in sand and gravel near to the river at Witherly.
So over centuries Stone Age, Bronze Age, Romans, Saxons, Danes and Normans all stamped a way of life on this area.
In the Domesday survey of 1086 Hartshill is known as Ardreshill. Thirteen families lived here at a time when tracks through the forest were deep and difficult to find.
Hugh De Hardreshill Was given the manor in 1125. It was he who built the first defensive system: a motte and Bailey,[a mound and enclosed yard,] here on this castle site, over looking Athestone. The walls were made of wood and on top of the motte was a wooden tower which was home to the Lord of the Manor and his family, as well as being a look~out post.
The first stone building at the castle was the chapel, built in the 13th century. Little of this remains above the ground. A hundred years later the wooden walls of the Bailey were replaced by Granite walls 4 feet thick and 15 feet high, pierced with cross loops in sandstone.
A section of water filled moat remains on the west side. The north door survives and there are traces of the west door but no indication above ground of the main entrance which would have been on the south side. One is tempted that there would have been a tower in the south~west corner.
A later Tudor house was built into the north~east corner about 1560 but of this only the south~east chimney stack remains with its timber frame and mud and wattle walls, was demolished in the 1950s.
