"Built nearly 600 years ago, Blarney Castle is one of Ireland’s most popular attractions. Its large tower house was typical of fortifications built between the 15th and 17th centuries, with 18-foot-thick walls that slope inward for stability and defense. Of course, most visitors come to the castle to kiss the famous Blarney Stone. According to legend, anyone who kisses the stone will have the gift of gab, and it's been kissed by countless famous politicians, musicians, and other notable figures." - Travel + Leisure Editors
