Where do art museums discretley store their paintings?

Art museums typically store their paintings in climate-controlled storage areas, often referred to as art vaults or collections storage. These spaces are designed to protect the artworks from environmental factors such as humidity, light, and temperature fluctuations. Paintings are usually kept in archival-quality materials, such as acid-free boxes or protective wraps, to prevent damage. Access to these storage areas is usually restricted to authorized personnel to ensure the safety and preservation of the artworks.
