Parc y Meirw

View from the south east.

A single stone row measuring at least 911m long, including at least eight large-sized orthostats situated on south and west facing slopes. Unequal spacing indicates that it is very likely that many more have been removed. The row is orientated ESE to WNW, has both sea and landscape reveals and may even have once extended further eastward. Traditionally the row has been seen as consisting of the four western stones which are set relatively close together.
