To every pair of chapels there was a tower six stories high, approachable by a winding stair on the outside.

In the center stood a tower twice as big as the others, which rested on arches.

The vaulting was of blue sapphire, and in the center was a plate of emerald, with the lamb and the banner of the cross in enamel.

All the altar stones were of sapphire, as symbols of the propitiation of sins.

Upon the inside of the cupola surmounting the temple, the sun and moon were represented in diamonds and topazes, and shed a light as of day even in the darkness of the night.
