Volubilis is a UNESCO World Heritage Site located in a fertile plain at the foot of the Jbel Zerhoun (jbel = mountain), in the northwest of our mystery country.
From about 300BCE, Volubilis was the capital of the indigenous Berber kingdom of Mauritania. In 44CE, the area became the Roman province of Mauritania, with Volubilis as its capital. As a Roman provincial town, Volubilis was about as far out in the sticks as you could go. Despite this remoteness, it developed into a fine little city. Evidence of large-scale cultivation and processing of grains and olives suggests the area was something of a bread-basket for Rome.
Can you name that country?
