Metropolitan Cathedral of Valencia (institutional record)

This is the Metropolitan Cathedral of Valencia's own custodial record for the Santo Caliz, the Holy Chalice it has held in its Chapel of the Holy Chalice since 1437, describing the cathedral's construction, governance and continuous custody of the object. As the relic's legal and devotional custodian, the cathedral's own record is the correct source for its display history and the cathedral's official account of the object. Its limit is that it is a custodial and devotional record from the holding institution rather than an independent archaeological study of the cup's actual age or its claimed identification with a first century vessel, a question that needs an independent scholarly source addressing the object's material dating directly.
