Why do conservators usually preserve murals in their original architectural locations?

Conservators prioritize preserving murals in their original architectural locations because these works are considered "site-specific," meaning they are physically and aesthetically dependent upon their surrounding environment.1

Because murals are often executed directly onto primary wall supports—such as plaster, masonry, or stone—they are integral to the building in both a material and aesthetic sense. The art conservation community maintains that the character of the original site is essential to the work's meaning; removing a mural from its intended context can lead to a significant diminishment of that meaning and the public's ability to appreciate the piece as the artist intended.1

Furthermore, mural painting is unique as a form of pictorial art because it is organically connected to architecture, often modifying or partaking in the spatial proportions of a given room or structure. Consequently, conservation efforts are typically holistic, focusing on the maintenance of the building's materials alongside the painting itself to ensure the long-term stability of the work within its original setting.213
