The Cathedral of St John the Evangelist is included as a current Catholic cathedral in Portsmouth, England. Its place in the map is therefore defined by both city and church tradition: this is a Catholic cathedral belonging to the Catholic Church in England and Wales. That distinction separates it from St John’s Cathedral in Oban, which the supplied material identifies as Scottish Episcopal, despite the shared dedication to St John.

The review coordinates place the Portsmouth cathedral at 50.800345, -1.094290 in Portsmouth, United Kingdom. They provide the map’s grounded geographic anchor, while the named identity prevents confusion with other churches carrying the same dedication. The entry should not be merged with a similarly titled cathedral elsewhere simply because “St John the Evangelist” is a recurring cathedral name.

The supplied facts do not describe the building’s architecture, history, artworks, worship schedule or arrangements for visitors. Its significance within this guide is consequently precise rather than expansive: it is a current Catholic cathedral in the mapped English set, located in Portsmouth.
