No, the Royal Vault at St George's Chapel in Windsor Castle is not refrigerated. Unlike modern morgues, the vault is a traditional stone burial chamber located approximately 16 feet beneath the chapel floor. Preservation of the remains within the vault relies on lead-lined coffins. By sealing the inner wooden casket inside a heavy lead shell, the process of decomposition is significantly slowed by preventing the ingress of air and moisture. This centuries-old tradition ensures that the remains are preserved in a dignified manner without the need for modern mechanical cooling. The vault currently houses the remains of 25 members of the Royal Family, including King George III, IV, and V. However, it is important to note that many recent monarchs, including Queen Elizabeth II and Prince Philip, are not in the main vault; they are interred in the King George VI Memorial Chapel, a smaller stone annexe where their coffins are placed within a sunken stone grave beneath a ledger stone, similarly protected by lead lining rather than refrigeration.
