Founded c. 1030 by Sitriuc Silkenbeard, the Norse King, this Cathedral has a long and fascinating history. Among its treasures is the Royal Plate given by King William III in 1697 as a thanksgiving for his victory in the Battle of the Boyne. The crypt at over 63m long is the largest in Ireland and Britain and is open for visitors.
Situated in the heart of Dublin in medieval times, its high ground location enables it to be clearly seen from surrounding streets and the river Liffey. It has distinctive bells (19 in all), which can be rung by visitors during the guided tour at certain times, are sounded for Sunday services at 10:00 and 14:30 and for practice ringing by the bellringers on Friday evenings.
