Chellah ruins

The necropolis of Chellah, Chella or Sala Colonia is a necropolis and complex of ancient and medieval ruins which lie at the outskirts of Rabat. On this site the ancient Romans set up the outpost of Sala Colonia, which became a thriving city with several monuments. In the 13th century the Merinid sultan Abu al Hassan built a necropolis on top of the Roman site and surrounded it with defensive walls. Many of the structures in Chellah were damaged or destroyed in an 18th century earthquake.
