Arundel Cathedral belongs in this map because it is identified as a current Catholic cathedral of the Catholic Church in England and Wales. Its place in the collection is therefore defined by present institutional status, not by a claim about architectural fame or historical importance. For readers choosing by denomination, it is one of the two Catholic entries in this opening selection, alongside Brentwood Cathedral.

The entry is located in Arundel, United Kingdom, at the supplied review coordinates 50.855200, -0.559000. That gives the map a clearly defined southern English point and distinguishes it from the similarly Catholic Brentwood entry, which is in Brentwood, Essex. The two should not be treated as interchangeable: each has its own named town, coordinates and cathedral identity.

The supplied material does not provide opening hours, worship schedules, prices, architectural details or visitor facilities. Those are practical and interpretive questions to verify separately. What can be noticed with confidence is the combination of a specific Arundel location, Catholic affiliation and inclusion in a map limited to current Anglican and Catholic cathedrals and co-cathedrals.
