St Columb’s Cathedral is included as a current Church of Ireland cathedral in Derry. Its place in the guide rests on that explicit church identity and location, giving the Northern Ireland section an entry that should not be collapsed into the Catholic cathedral also listed in Derry. The complete name is the safest starting point for any map search or further research.

The Derry setting creates the most important comparison in this group. St Columb’s Cathedral and St Eugene’s Cathedral are separate places, represented by different verified identities and different review coordinates. For St Columb’s, the coordinates are 54.993889, -7.323056, and its verified identity is Q2558810. Retaining the apostrophe and the full saint’s name helps prevent a city-only search from producing the wrong result.

The supplied information establishes current status, Church of Ireland affiliation and Derry location, but it does not describe the building’s design, history, interior, opening arrangements or worship schedule. Its value for this map is therefore its clear institutional and geographic identity: a current Church of Ireland cathedral in Derry, distinct from the other Derry entry.
