क्राइस्ट चर्च कैथेड्रल
Christ Church Cathedral is Dublins oldest building still in daily use, founded by the Viking King Sitric Silkenbeard around 1028. The current medieval stone structure dates from the 12th-13th centuries and serves as the cathedral of the Dublin and Glendalough diocese. Its highlight is the 12th-century crypt - the largest medieval crypt in Britain and Ireland - which contains the famous mummified cat and rat, treasury, and fascinating exhibits.
