St Patrick's Cathedral, Dublin

St. Patrick's Cathedral, built to honor the patron saint of Ireland, is a must-see attraction in Dublin. It stands adjacent to the well that it is said St. Patrick himself used to baptize converts. The original wooden church was erected in this spot in the 5th century but was rebuilt at the end of the 13th century to reflect its boost to cathedral status. Some repairs were done in the 1800s but the original style was maintained well enough to make it unclear as to how much of the medieval structure remains.

York Minster - Yorkshire, England

Ranking high on the list of York’s top attractions, the magnificent York Minster is one of Europe’s finest cathedrals and the largest medieval cathedral in the UK. Although the earliest parts of the building are from the 12th century, the Minster’s roots date back much earlier, with the present day cathedral built on the site of a former Norman church and Roman fortress. A masterpiece of gothic architecture, the Minster is renowned for its stonework and exquisite stained glass windows, as well as its fine acoustics.
