|Not a sinner about the place - literally|
As you walk around you can't help notice the strange little towers from time to time, like this one above. Obviously a look-out sort of thingmy, with small openings to peer through and see if your enemy is coming at you with a loaded musket, or whatever they had to throw at you in those days. The one above is just opposite St Columb's cathedral - hence the caption.
