This oval structure, measuring roughly 14 metres northwest to southeast and 8 metres across its width, is defined by what remains of a stone wall that once stood about a metre thick. Today, these walls appear as low, moss-covered banks of stone, barely 30 centimetres high in places and so weathered that sections have all but disappeared into the landscape.

The interior of the enclosure holds an intriguing feature; a band of moss-covered stones runs east to west through its centre, dividing the space in two. Whether this represents the ruins of an internal wall or simply exposed bedrock remains unclear, adding to the mystery of the site’s original purpose. The enclosure’s weathered state and the growth of moss across its stones suggest considerable age, though without excavation, its exact date and function remain unknown.

This isn’t an isolated monument; two similar enclosures lie nearby, one 40 metres to the northwest and another 25 metres to the northeast, suggesting this area of Cavangarden may have been a significant settlement or agricultural site in antiquity. The clustering of these structures hints at a landscape that was once carefully organised and actively used, now returned to rough pasture but still bearing the marks of its ancient inhabitants.
