Acid rain can damage buildings, historic monuments, and statues, especially those made of rocks, such as [[limestone]] and [[marble]], that contain large amounts of calcium carbonate. Acids in the rain react with the calcium compounds in the stones to create gypsum, which then flakes off.

The effects of this are commonly seen on old gravestones, where acid rain can cause the inscriptions to become completely illegible. Acid rain also increases the [[corrosion]] rate of metals, in particular [[iron]], [[steel]], [[copper]] and [[bronze]].<ref>{{cite journal|last1=Reisener|first1=A.|last2=Stäckle|first2=B.|last3=Snethlage|first3=R.|year=1995|title=ICP on effects on materials|journal=Water, Air, & Soil Pollution|volume=85|issue=4|pages=2701–2706|bibcode=1995WASP...85.2701R|doi=10.1007/BF01186242|doi-access=|s2cid=94721996}}</ref><ref>{{cite web |url=http://www.iiasa.ac.at/Admin/PUB/Documents/WP-89-104.pdf |title=Approaches in modeling the impact of air pollution-induced material degradation |access-date=November 18, 2010 |archive-url=https://web.archive.org/web/20110716175635/http://www.iiasa.ac.at/Admin/PUB/Documents/WP-89-104.pdf |archive-date=July 16, 2011 |url-status=dead }}</ref>
