The Caesar Hotel in London exhibits a major collection of Roman mosaics from the 2nd-6th centuries, which forms part of the art collection of Derby Hotels Collection. These mosaics, most of which come from the Roman province of Syria and the renowned workshops of Antioch, are permanently displayed in the public areas of the hotel.

The collection is completed by originals, collages and lithographs by the Catalonian artist, Francesc Guitart, created especially for the hotel.
