The House of Orpheus is one of the most impressive of the great mansion houses in Volubilis, and a good first stop on the lower section of the site. It contains three substantial mosaic floors in a remarkable state of preservation: the Orpheus mosaic showing the mythic musician surrounded by animals, a Amphitrite mosaic depicting the sea goddess in a chariot, and a floor of dolphins. These are among the largest and finest mosaics still visible in situ at Volubilis — most of the site's other mosaics have been relocated to the Rabat Archaeological Museum.
The house follows the standard Roman atrium plan: a central courtyard with a pool, reception rooms to one side, and private quarters beyond. The scale of the building reflects the wealth of the city's merchant class, who grew rich trading olive oil, wheat, and wild animals exported to Rome for the arena.
