Immediately on entering, before anything else
Plan on thirty to forty-five minutes with both the crypt and the embrace
Go straight down the stair to the crypt beneath the high altar, where a silver urn holds the remains venerated since the ninth century as those of the Apostle James. This is why the cathedral was built, why the roads were made, and why you are standing in Galicia. Catholic tradition in Spain holds that the Apostle's body was brought here after his martyrdom in Jerusalem and that the tomb was identified in the ninth century near Iria Flavia. Eternal Roam presents that as an ancient and continuous tradition honoured by centuries of pilgrims, not as a claim of modern forensic certainty. What is beyond argument is that people have prayed on this spot for eleven hundred years. Afterwards take the stair behind the high altar and make the traditional embrace of the Apostle's statue. The route runs down and then up, and that shape is the whole devotion.
Give your time to the crypt first, the embrace second, and the architecture a distant third.
