The history of Port-Louis has always depended on its exceptional situation : a natural harbour between the river Blavet in the West, and the river of Etel in the East. The peninsula of Port-Louis is constituted by a granitic spur which makes its access difficult and requires a good knowledge of the tide streams and the rocky shores.

This is justified by an old saying : " He who enters here is a fool "

In this part of the country where the rivers are so short, the Blavet can be perceived as an important communication route from land to sea.

Port-Louis, between Nantes and Brest, is the only harbour accessible to all tonnage ships, in all weathers, with a good map of the sea bed !

Port-Louis has benefited from :

  • an excellent strategic situation
  • the military vocation of a fortified city

People have been living there since prehistoric times.

Numerous vestiges are evidence of this settlement.
