Chellah

The Chellah or Shalla, is a medieval fortified Muslim necropolis and ancient archeological site in Rabat, Morocco, located on the south side of the Bou Regreg estuary. The earliest evidence of the site's occupation suggests that the Phoenicians established a trading emporium here in the first millennium BC. This was later the site of Sala Colonia, an ancient Roman colony in the province of Mauretania Tingitana, before it was abandoned in Late Antiquity.
