That kind of physical merger is relatively uncommon, and it raises quiet questions about whether the two were planned together, or whether a second burial was deliberately placed beside an existing one, the later community choosing proximity to whatever the first mound represented.

A ring barrow is a low funerary mound, typically of Bronze Age origin, consisting of a central raised area surrounded by a circular ditch, known as a fosse, and an outer bank. At Garrane, the more southerly of the two is modest in scale, a circular area of roughly five metres in diameter, enclosed by a fosse only around sixteen centimetres deep, with an external bank of similar height. These are subtle features at this point, worn down over millennia of grazing. What makes the site more than just a faint earthwork is where its bank meets the bank of its neighbour to the north, the two structures conjoining from the north-west around to the north-east, the boundary between them effectively dissolved. That shared edge is the clearest evidence of a deliberate relationship between the pair, whatever that relationship may have been.
