Chellah

The Chellah or Shalla (Berber languages: Sla or Calla; Arabic: شالة) is a medieval fortified necropolis and ancient archeological site in Rabat, Morocco, located on the south (left) 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. The earliest building activities in Sala’s civic district date back to the Kingdom of Mauretania, 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. In the late 13th century the site began to be used as a dynastic necropolis for the Marinid dynasty. By the mid-14th century Marinid sultans had enclosed a part of the site with a new set of walls and built a religious complex inside it to accompany their mausoleums. In the 15th century the necropolis began to decline and it suffered damage over the centuries due to earthquakes and looting. Archeological excavations in the 20th century unearthed the remains of the ancient Roman town. Today the site is a tourist attraction and since 2012 it forms part of a UNESCO World Heritage Site.
