Does acid rain have affect in architecture?

Answer 1

Yes, if the architecture is on the surface. Yes it does, and a very serious one. Acidic rainwater corrodes stonework and masonry, rapidly increasing wear and deterioration in buildings. Different types of stone are affected to different degrees (for example, buildings or structures made of soft stone, such as sandstone, are a lot more badly affected than those built of harder stone, such as granite etc.) but ALL stonework is damaged to some degree or another. Marble is especially quick to deteriorate.

Acid rain is a particular threat to ancient or Mediaeval structures, such as the buildings and ruins that survive from Greek or Roman times, and also the beautiful Mediaeval cathedrals of Europe. These have already suffered from considerable wear due to their great age and the passage of time, so will be worse affected than comparatively newer, 'fresher' buildings (i.e. from Victorian times, etc.)
