Walk of the week: Cathedral ruins lie on Ardmore route

WE set off on the road signposted Duncrone B&B, directly opposite the Round Tower. We will explore the cathedral and tower, major features of interest, on our return.
The wall on our right carries two shield-like iron ties, and supports swathes of purple valerian in summer. Far to the north we see the Knockmealdown Mountains. This road has overgrown ditches with a wealth of wild plants. We pass a high stone wall, probably once bordering a substantial demesne.
