The Catholic Chapel at the Cadet Chapel is necessarily more like a grotto chapel with a flat roof, since it is beneath the Protestant Chapel.  Its acoustics are far better than the Protestant Chapel, and it has a spectacular mosaic altar wall, and very unique representations of the stations of the cross, as you will see.

The sacristy box for the eucharistic elements is seen above.

 

One of the most interesting aspects of the Catholic chapel is what is positioned in the aisles near the back of the chapel.

What you see in the back of this shot is the famous holographic 3-D image of the image on the Shroud of Turin.
