GeoGraph - photograph every grid square

This is the meeting point of the three counties of Carmarthenshire, Swansea and Neath-Port Talbot.
The photo is taken from within Carmarthenshire, whose edge runs in from the right of shot to touch the junction and head out directly left.
The small road leading upward and left forms the boundary between Neath-Port Talbot on the left and Swansea on the right.
