The lower chapel has an amazing acoustic based on a system of vases inserted in the depth of the wall at the bottom of the chapel on one hand, and also based on the overall inner shape of the building. The result is amazing: someone whispering at the entrance of the chapel can be heard at the bottom as if whispering in the ear of the listener...!
