"This castle was built around 1190 by the Norman baron Hugh de Lacy, and it was later seized by King John of England (and for that reason, the castle is sometimes called King John’s Castle). Located in County Louth on the southern shores of Carlingford Lough, the castle is a short walk from the village of Carlingford, a walled town famous for its medieval buildings. Two rectangular towers in an enclosed courtyard were part of the original castle, and many changes have been made over the years. Guided tours are available from March to October." - Travel + Leisure Editors
