There is an interesting place about 15 kilometers from the center of Kénitra - the ruins of Thamusida, which was a major river port that flourished in the Roman era of Morocco.

Archaeologists, who have been working on the territory of the ancient monument for several decades, claim that the port appeared here in 200 AD. At that time, the Romans dominated this territory, and they needed a place where they could leave their ships, store ammunition, trophies, and, of course, various goods that were later sent to the Italian cities for sale.

For the construction of such a strategically important object, the Romans chose a Berber settlement. Firstly, there were already residential buildings that could be temporarily occupied. Second, after the occupation of the territory, the military began to use the inhabitants as labor: forced labor was common here.

Thamusida grew every year. And from a small, but strong port, it turned into a rather impressive settlement. There was a temple for worshipping Venus, besides, there were buildings for public meetings, baths, and a library. The houses of the poor and the industrial buildings were strictly separated from the houses of the nobility: the precise planning of the streets made it possible to do this without the slightest difficulty. Later, the city was surrounded by a high stone wall, which fenced off an area of 15 hectares from the outside world.

In the third century AD, Thamusida became the main Christian city on the territory of Morocco with a population of more than 7,000 people.

The decline of this luxury city began after the Romans had moved their trade routes. Gradually, people began to leave their homes in search of work and a better life. The last inhabitants left the city around 425 AD. After that, there were several raids of vandals who plundered the treasures of ancient Thamusida, leaving only the stone buildings.
