The Cross of Blackrock
Now situated on the pavement outside Bank of Ireland, this 12th century granite cross was moved here from some unrecorded church site in the locality. It is finely shaped with chamfered edges and is unusual in that it bears no Crucifixion scene, instead there is a head carved in high relief. On the opposite face is a curious abstract incised pattern.
The ancient cross was used to mark a point on the boundary of the City limits. Until the middle of the 19th century it was customary for the Lord Mayor of Dublin to ride round the boundaries of his jurisdiction - this was known as Riding the Franchises. The ride was arduous going through ditches, across rivers and through people's houses when they got in the way!
