Water Damage
Another problem the restoration workers faced was water damage that had made its way into the ruins. Firefighters were instructed to aim water away from the ancient and quite fragile stained glass windows. However, they weren’t able to do the same for the stone vault, which was directly threatened by the fire.
An Unstable Structure
Firefighters aimed the hoses directly on the limestone, causing the porous material to fully absorb much of the water. This led to increased weight, and even a year later, the structure has not fully dried out. The water trapped in the stone also expands or contracts (depending on the temperature), creating even more uncertainly to the already unstable building.
