An intricate safe built in 1872 by the Morosini brothers in Milan has been fully restored by Döttling manufacturers and is now available.

The safe built to store a safe—yes you read that correctly—was originally commissioned by Victor Emmanuel II, who ruled Italy from 1861 to 1878. After 19 months of delicate restoration, the unique piece of art is back in tiptop shape.

The Italian king’s safe was rumored to be used to store love letters and gifts from Rosa Vercellana, his second wife. Since she was only 14 years old when their relationship began—also while he was still married to his first wife, Queen Adelaide of Austria—tokens from the relationship had to be kept hidden.

With two Medusa-esque plaques decorating the exterior, which are said to be inspired by Rosa, the unique safe features a secret mechanism that must first be engaged before the keyhole is exposed.

Available at Döttling, the one-of-a-kind safe is sure to sell quickly.
