Inside the cathedral just after watching the Mirhad, we visited the Cathedral museum, where you can see some of the Corpus Christi that are taken in processions, some relics, etc.
Another chance to enjoy the mix of modern, antic differences in the same place.
Out of the museum you will find the best area for photos as it has more light than the other side, if you see all the VT photos you may think … Did all the VT’s stopped in the same place for the same photo? hehehe
There are many chapels along the inside of the S. wall of the Mezquita as well as many pieces of history and art. (The entire building is considered a museum since they charge admission but the labelling and signs are few and scanty). The valuable church items are in the Treasury which is the Capilla de Santa Teresa which is Baroque with a dome to match. I knew of no helpful guide so I remain ignorant, but you cannot miss the 2 1/2 meter tall Gothic monstrance-reliquary(early 16C) of gilded silver in a giant case in the middle of the circular chapel. It looks like a Flemish belfry and is by a goldsmith of that region named Henri de Harpe.(It is hard to get far enough away to photograph because so many people crowd in front of you, even off-season). There are many other valuable objects displayed as well as pieces of carved stone, paintings of modest note and a giant music stand that must have once been in the Coro.
The Tesoro (Treasure) it´s located in a small chapel, several works of art mainly religious including the beautiful Custodia of gold and silver designed by German artist Enrique de Arfe (1510).
