This stone was shown as such on the 1888 and 1906 revisions of the OS maps, but not since. It marks the otherwise invisible boundary between the parishes of Eglwyswrw (right) and Meline (left). It also marks an eastern boundary of the Pembrokeshire Coast National Park; most of Eglwyswrw is outside the park.
The boundary here is typical of boundaries in the area; it follows a glacial meltwater channel running south to north. Small streams running southward and northward from this point mark the boundary. The road marks the high point along this line, hence the need for a stone.
