The roadstead of Brest (
Strategic importance
For a number of centuries, Brest has been an important military port. The easily defensible roadstead of Brest therefore has a number of military installations, for example:
- Brest arsenal, on the north of the bay;
- the submarine base of the Île Longue, to the south-west;
- the École Navale naval college and the Poulmic association of schools at Lanvéoc;
- the naval 'graveyard' for ships at Landévennec.
One can also find many remains of old military fortifications and other ruins from past centuries, like the forts at Portzic, at pointe des Espagnols, etc.

Environment
Thanks to its layout, the roadstead harbours a wide diversity of natural habitats and a high level of biodiversity. It also includes many sites of importance for birds,[1] several networks of habitats and underwater corridors and coastal areas of importance. These areas have been greatly affected by the human activities in the north-west, but have justified the classification of around half of the roadstead as a zone in Natura 2000.[2]
Pollution
The rich ecology of the roadstead has been diminished by the past exploitation of certain resources, and by the presence of a number of pollutants including
The roadstead is also a victim of the after-effects of war, and in particular the waves of pollution from the
