St. Patrick’s Cathedral was founded in 1191 by Archbishop John Comyn on the site of a well where, according to tradition, St. Patrick baptised the infidels. The building we see today was primarily constructed between 1220 and 1259 in the Gothic style but was extensively renovated in the late 19th century to address serious structural problems. St. Patrick’s is the largest cathedral in Ireland and is inextricably linked to the country’s history for the past 800 years.
