Caja de las Letras

The Instituto Cervantes, taking advantage of the presence of the vault in the basement of its headquarters (Caryatid Building) in Madrid (Spain), uses safe deposit boxes for great figures of Hispanic culture to deposit a legacy that will not be opened until the date they decide. Said compartments would thus perform the functions of a time capsule. The aforementioned building has a vault for having been the former headquarters of the Spanish Central Bank.
