One of them, a ring barrow near Palmerstown, has been pressed into service as a sand trap in front of the first green, which is perhaps one of the more unusual second careers an ancient funerary monument has ever had.

A ring barrow is a burial mound of the Bronze Age type, typically consisting of a raised central mound surrounded by a circular ditch, known as a fosse, and an outer earthen bank. This particular example measures around twenty metres in diameter overall, with the central mound itself spanning roughly five metres across. The fosse and outer bank are still present, though the bank has been considerably worn down over time. The central mound has suffered more obvious interference; it has been dug out from the north-west around to the east, leaving it horseshoe-shaped in plan rather than the full circle it would originally have formed. Exactly when or why this excavation took place is not recorded, though disturbance of this kind was common across centuries, whether through curiosity, the search for treasure, or later agricultural activity. The site is noted as being in fair condition overall, which, given that it sits on a functioning golf course and has been partially hollowed out, is perhaps as much as could reasonably be hoped for.
