BENCHMARKS continued
Benchmarker is not so sure but having studied the 25” map, M.C. is convinced that this is the 'mark that should be on St Mary's Chapel of Ease, - a.k.a. the Black Church - on Mountjoy Street in Dublin. And M.C. includes a likely story “according to local legend if you walk counter-clockwise round the church three times at midnight, you will summon the devil”. Wonder has M.C. been supping the devil's buttermilk?
