St Patricks Cathedral

Ireland's largest church was founded beside a sacred well where St Patrick is said to have bapized converts around AD 450. A stone slab bearing a Celtic cross and covering the well was unearthed at the turn of the 20th century. It is now preserved in the west end of the cathedral's nave. The original building was just a wodden chapel and remained so until 1192 when Archbishop John Comyn rebuilt the cathedral in stone.
