Ireland has more than 30,000 castles, tower houses, and fortified sites — more per square mile than almost anywhere in Europe. Behind every one of them is a family, a sept, a clan that built it, defended it, and in many cases, lost it.
This free tool matches your Irish surname to the castle that your ancestors were most associated with, and tells you where it stands today. Some are world-famous visitor attractions. Others are ruined towers in a farmer’s field, still waiting to be found.
