This reminds me of the Spencer Tracy film, "Bad day at Blackrock" so the question is which Blackrock is it. A really nice Mason shot to start this week.
Identified the Location as Blackrock Co. Dublin. She tells us that "The cross used to mark the boundary of the city of Dublin:
In the centre of the village is a large block of granite, on which are the remains of an ancient cross; to this spot, which is the southern extremity of the city of Dublin, the lord mayor, with the civic authorities, proceeds when perambulating the boundaries of his jurisdiction."
