Painted with the light of a torch on a round tower in a local church yard late at night. If you look carefully you can even see stars in the sky! This page has some information about that tower:
The round tower in Waterloo (approx. 1 mile from Blarney) … … was built in the 1800’s by Fr. Matt Horgan, the then parish priest of Blarney.
Here’s a picture from the front of that building!
