クライストチャーチ大聖堂
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.
