One thing that most historical buildings in Europe have in common is the beautiful carvings and statues. Many of the cathedrals we saw in England and France were made of limestone. Limestone was fairly easy to obtain, can be cut into blocks and is long lasting. But the biggest attraction for using this stone for these large buildings was that it was easy to carve. Unfortunately, limestone reacts to acid and many statues and buildings are being destroyed by acid rain and erosion. Several of the cathedrals had renovation projects underway to restore or replace areas that were eroded.
These carvings show a multitude of angels surrounding Christ in the center of the arch, above the doorway at the Notre Dame Cathedral in Paris.
