not far away at Lechlade, Gloucestershire. During this era of the Industrial Revolution in the United Kingdom the local towpath would also have become heavily worn year-round for the first time. The longer Thames Path, variants of which were first made in the 19th century, crosses the bridges. Matilda's Castle Time Team, in a programme first broadcast on 15 February 2009, excavated Matilda's Castle in the summer of 2008. They found that visible earthworks near Radcot Bridge dated from the 17th-century English Civil War, when Parliamentary forces built them to support cannon used to bombard Royalist forces garrisoned in Radcot House. Underneath some of these earthworks were remains of a square Norman keep dating from the time of the 12th-century Anarchy. Evidence suggested the tower was pulled down a century after it was built. Its remains were further damaged by later constructions on the site. Some Roman remains, possibly from a villa, were also found.
