Ruins are the remains of human-made architecture: structures that were once intact have fallen, as time went by, into a state of partial or total disrepair, due to lack of maintenance or deliberate acts of destruction. Natural disaster, war and population decline are the most common root causes, with many structures becoming progressively derelict over time due to long-term weathering and scavenging.
