Which saint's cathedral in Dublin is traditionally built beside a well associated with Saint Patrick?

St Patrick’s Cathedral in Dublin is traditionally built beside a well associated with Saint Patrick.

The cathedral stands on a site where tradition places a holy well used by Patrick for baptizing converts. A small early church was associated with the location before the present cathedral developed. The medieval cathedral was founded in the late twelfth century and became one of Dublin’s major religious landmarks.

St Patrick’s Cathedral is the national cathedral of the Church of Ireland, an Anglican church. It should not be confused with Christ Church Cathedral, another historic cathedral in central Dublin, or Saint Patrick’s Cathedral in New York City.

The site’s connection with Patrick is traditional and belongs to the layered history of Dublin’s religious landscape. The cathedral’s present Gothic architecture reflects medieval rebuilding rather than the appearance of the earliest church associated with the well.
