The monument comprises the remains of a defended enclosure, which probably dates to the Iron Age period (c. 800 BC - AD 43). The enclosure is located on a coastal promontory above the sea that marks part of the defensive circuit. The construction of a rampart placed across the neck of the promontory divides it from the mainland. Castell Bach is sub-rectangular, measuring c.110m east-west by between c.60 and c.74m. The rampart on the east is c.80m long, with a 1.8m high bank and 1m deep ditch, and it has a causewayed entrance near the centre. The remaining sides are defended by scarps above steep natural slopes.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, layout, building techniques and functional detail.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
