The Getty and the Institut National du Patrimoine of Tunisia train conservation technicians to clean, monitor, and maintain mosaics so that they can be seen and studied in their original settings. From the first to fifth centuries AD, the Roman province of Africa Proconsularis was a major economic force in the Roman Empire. Luxurious houses and public buildings were embellished with elaborate mosaic paintings. Many of these mosaics are now housed in the collections of the National Museums of Tunisia.
