Architectural conservation aims to maintain and prevent damage to objects of cultural significance through carefully planned projects. It requires a team with expertise on the objects who collectively decide the best course of action. The conservation movement began in the 19th century with the industrial revolution's demolition of historic buildings. This led to the founding of the Society for the Protection of Ancient Buildings in 1877, marking the start of modern preservation efforts. John Ruskin was influential in identifying the values of historic buildings and establishing foundations for modern conservation philosophies.
