A lovely remnant of medieval Cork hidden down a Victorian terraced street. There's not much remaining, just a tower, but it's free to visit and an architectural cracker. There's a board beside it with information on the history of the abbey that's well worth reading too. Make sure to also visit the nearby Elizabeth Fort at the same time, as both compliment each other well and give you a glimpse into what Cork once was.
