Wigmore Castle is a mid 11th century earthwork motte and bailey fortress, founded by William fitz Osbern. Overlooking the earthworks of Green Hill, in the 13th century the Mortimer family founded the stone castle. Held by Sir Robert Harley for Parliament in the Civil War but he could not garrison it, so it was slighted to stop it being seized for the crown.This large castle is encased by a great ditch and has towers and curtain walls surviving to their full height, after the consolidation of the entire site. The buildings have been left buried to there first floor level, so the gate passage of the two storey gatehouse can only just be walked through. At the highest point stands the motte, with the impressive remains of a shell keep and a stair tower, standing to four storeys. 4 miles north-east at Pipe Aston is Aston Tump and 5 miles south-east at Kingsland is Croft Castle.
