St Briavels Castle

Highlight • Castle

St Briavels (pronounced Brevels, once known as 'Ledenia Parva' (Little Lydney), is a medium-sized village and civil parish in the Royal Forest of Dean in west Gloucestershire, England; close to the England-Wales border, and 5 miles (8 km) south of Coleford. It stands almost 800 feet (240 m) above sea level on the edge of a limestone plateau above the valley of the River Wye, above an ancient meander of the river. To the west, Cinder Hill drops off sharply into the valley. It is sheltered behind the crumbling walls of the 12th century St Briavels Castle.

Slade Brook Travertine Dams

Highlight • Natural Monument

This remarkable series of dams (at least 60) occurs over nearly half a mile of Slade Brook. They completely dam the stream, which is from 3 to 30 ft wide, and range from about 1 to 18 inches in height, with an average of about a foot. Such dams are formed when spring water, near-saturated in lime, runs over obstructions in the stream bed, when loss of dissolved carbon dioxide results in deposition of travertine (a porous, friable type of limestone). Development of dams may well have been initiated by water running over accumulations of twigs and branches across the stream. The dams are colonised by various species of moss and algae, which become encrusted by travertine as the dams build up, and they have considerable conservation value. Most of the water in the stream is discharged from a large spring, which emerges from the Carboniferous Limestone bedrock near the head of the valley. The Slade Brook dams are possibly the best example of such structures in the country. On no account should they be touched, as they are easily damaged.
