Chepstow, literally on the Welsh border, in Monmouthshire was a Norman castle, construction beginning in 1067CE as part of a chain of defences along the Marches. The castle was later used as a spring board for the Norman conquest of Gwent and remained a strategic point until the Reformation though was becoming used more for accommodation by the 16th century. By the 1700s it had fallen into decline and gradual decay.
The castle is located on the river Wye and is located on a limestone ridge. The castle has been expanded since it's beginnings, having four bailies at it's height. Strongpoint of the castle was the Great Tower which was completed in about 1090.
