Tidenham Parish is a large Parish at the Southern extremity of the Forest of Dean District, in Gloucestershire, on the borders of Monmouthshire, close to the town of Chepstow and the Severn Bridge. The Parish has grown up at the confluence of the rivers Severn and Wye, at an important crossing point of these rivers, influenced by Ancient Britons, the Romans, King Offa, the Normans, Victorian engineers such as I K Brunel and in modern times by those who brought the Severn Bridge to the Parish.
The military influence has always been there throughout history, mainly due to the protection of the Wye crossing but also due to the ship-building industries and into the modern day with the Army Camp at Beachley.
For many centuries the parish was either a hunting ground or depended largely on agriculture, fisheries or the extractive industries of quarrying and timber.
Following the opening of the Severn Bridge in 1966 to replace the Aust – Beachley Ferry and more recently the new A48 Bridge across to Chepstow in 1988, the parish has been the site of significant residential growth, with high levels of commuting to South Wales and the Bristol area.
