Description

This is a section of the boundary wall at Plas Machynlleth, which includes the main entrance and extends up to the former coach house. The wall is not contemporary with the former coach house and stable range, as there is a visible break in the masonry. The main entrance features simple low gate piers, although the gates have been removed. The boundary wall curves inwards to the southwest and is splayed back to the northeast at the entrance. Beyond this corner to the northeast, the wall has been rebuilt at a later date. It is constructed of rubble with a flat coping.
