Île Longue

Île des Morts (Island of the Dead) is a 7-hectare island in the Bay of Roscanvel, to the south-west of the roadstead of Brest, between the Quélern peninsula and Île Longue. It is 26m above sea level at its highest point.

The roadstead of Brest (French: rade de Brest, French pronunciation: ​[ʁad də bʁɛst]; Breton: Lenn-vor Brest) is a roadstead or bay located in the Finistère department in Brittany in northwestern France. The surface area is about 180 km² (70 sq mi). The port of Brest and one of the two French naval bases, Brest Arsenal, are located on its northern edge. It is linked to the Atlantic Ocean (called the Iroise Sea at this point) by the Goulet de Brest, a strait about 1.8 km wide. Three main rivers drain into the roadstead: the Penfeld (the town of Brest and the first buildings of the naval base were built on its banks), the Élorn (or river of Landerneau) and the Aulne (or river of Châteaulin).

Roscanvel (French pronunciation: ​[ʁɔskɑ̃vɛl]; Breton: Roskañvel) is a commune in the Finistère department of Brittany in north-western France.

The siege of Fort Crozon or the siege of El Leon was a land and sea engagement that took place as part of Spain's Brittany Campaign late in the French wars of religion and the Anglo-Spanish War (1585–1604). The siege was fought between 1 October and 19 November 1594 and was conducted by English and French troops against a Spanish fort constructed on the Crozon Peninsula near Brest. After a number of assaults were repelled, a Spanish relief force under Juan del Águila attempted to relieve the garrison, but it was delayed by French cavalry and could not reach the garrison in time.An assault by the English using a deceitful ruse ended the siege when the defenders were all but put to the sword. The victory proved decisive in two ways. First, it denied the Spanish an important large independent base and port from which to operate in Brittany against the English and Dutch. Second, the Spanish had lost most of their support from the French Catholic League, and as a result enabled the French king Henry IV to declare war on Spain.

The Pointe des Espagnols is the north-east extremity of the Roscanvel peninsula, an outgrowth of the Crozon peninsula closing off the roadstead of Brest. It also marks the south-east limit of the goulet de Brest (the other limits are marked by pointe des Capucins, pointe du Petit Minou and pointe du Portzic). Formed by a cliff that is more than 60m high, at whose summit and base are the remains of fortifications and barracks, the point reaches towards the north-east via the rocher de la Cormorandière, marked by a pole. The straight channel situated between the point and the rocher is the location for strong currents which affect the roadstead. This strategic position, facing Brest, was already noted by the Duchy of Brittany, who sited a fortlet there in 1387 (now lost). In 1594, Spaniards landed here and were only dislodged after several battles - it was in this period that the cape first took on its present name.

The Île Ronde (literally Round Island) is a French islet 400 metres (0.25 mi) to the south west of Pointe de l’Armorique, in the roadstead of Brest, within the territory of the commune of Plougastel-Daoulas. Its highest point is 24 m. Facing Île Ronde, on the pointe de l’Armorique, is the fort de la pointe de l’Armorique, built in 1775 for the defense of Brest.

Lanvéoc (French pronunciation: [lɑ̃veɔk]; Breton: Lañveog) is a commune in the Finistère department of Brittany in north-western France. The École Navale, the French naval academy, is located here.

The fort Quélern or réduit de Quélern is a castle and prison in the commune of Roscanvel in France.

The canton of Crozon is an administrative division of the Finistère department, northwestern France. Its borders were modified at the French canton reorganisation which came into effect in March 2015. Its seat is in Crozon.It consists of the following communes:

The Fort de Portzic was built near the town of Brest by Vauban between 1693 and 1699 as part of the defences of the goulet de Brest. It faces the pointe des Espagnols and was improved and enlarged over time (including the Phare du Portzic in 1848 and a semaphore station in 1987), since it formed the town's last and innermost defence. The buildings on the site remain in military use. Nearby is the lighthouse Phare du Portzic.
