Hidden under the ash for almost 2,000 years, the mosaics that once adorned the wealthy homes and public buildings of Pompeii are now viewable by visitors to the site and museums around the world.
The artworks were found in a banqueting hall with dramatic black walls and a mosaic floor made of more than 1 million white tiles. Entry tickets to Pompeii start at €18 (£14.90; $19.30).
