BENCHMARKS continued
This one is located at the base of the southernmost railings pillar at the front of Saint Patrick's Cathedral in Dublin City. This location demonstrates one way in which 'marks are gradually being lost; the level of the pavement here seems to have risen over time, and if the rate continues then this 'mark will probably be buried in 150 years or so.
