One of the most important buildings of the Capital has been converted into a luxurious hotel through the consolidation of different properties and a new design. The underground floor will become a meeting centre, a single space characterized by its relationship with the archaeological excavations of Diocletian’s Spa emerging from the building. The walls of the room are finished in a contemporary design, surmounted by brick vaulting. Large floor panels of steel and glass enable sight of the excavations.
