 It is unclear whether these chambers, which are only a few metres apart, were part of the same structure or were independent.A report in The Archaeological Journal in the mid-nineteenth century states that at that time the chambers were surrounded by a large number of small stones.Nowadays, this stone debris is no longer visible, but its former presence may indicate that at one time, both chambers were buried under a single mound, as is the case in the multi-phase burial tomb at Trefignath, some west of Presaddfed.
