Description
Summary Description and Reason for Designation
The following provides a general description of the Scheduled Ancient Monument.
The monument consists of the remains of a medium-sized auxiliary fort dating from c. AD 75 (Roman period). It is located on the Roman road from Neath to Brecon. It is best preserved on the west side where surrounding bank and two outer ditches are clearly visible. Excavations revealed a standard layout, with timber buildings inside. To the south are the remains of a probably earlier large marching camp (GM343). Roads can be traced leading to the south and east of the fort. The fort was abandoned AD 140-50.
The monument is of national importance for its potential to enhance our knowledge of Roman military organisation. The monument forms an important element within the wider context of the Roman occupation of Wales and the structures may contain well preserved archaeological evidence concerning chronology, layout and building techniques.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
