   The Community of Communes of the Pays d'Iroise, which is now called Pays d'Iroise Communauté ( PIC ), is one of the oldest in Brittany. It was created in 1992 by the transformation of the Syndicat Intercommunal à Vocations Multiples (SIVOM) of St-Renan, which had already brought together 11 communes since 1989.
In 1994, the municipality of Ile-Molène also joined it. Then in 1997, the dissolution of the SIVOM of Ploudalmézeau led to the accession of 8 new municipalities. In 2016 two of them decided to merge.
Pays d'Iroise Communauté currently has a population of 49,461 over an area of 317 km2, i.e. 156 inhabitants per km2.

   Brélès, Brelez in Breton, means plateau where justice is done. One thinks, of course, of the columns of justice near the castle of Kergroadez, but the name of the village is much older and could, according to Fréminville, refer to a feudal mound that has disappeared today, named Castel-Mériadec, near the Aber Ildut river. Plourin's parish part under the Ancien Régime, Brélès became a commune during the Revolution.
Known for its old houses, castles and manor houses as well as the triumphal arch giving access to its church, Brélès has added some modernity under the form of a granite statue, the Brélès Lady, as well as the organization of a great Breton wedding, every year, on August 15th.
   Today, covering an area of 14 km2, it's a farming community of 860 inhabitants that's increasingly turning to tourism and showcasing its rich heritage.

Molène est connue depuis la Préhistoire. Des fouilles entreprises tout près de son littoral ont montré que l'île était déjà pleinement occupée à l'âge du bronze, alors que le niveau de la mer n'était qu'à 3m au-dessous du niveau actuel. 2000 ans avant notre ère, on y accédait donc en bateau. Molène tire vraisemblablement son nom du breton moul-enez, l'ile en forme de colline arrondie ( moul = meule ). Ancienne dépendance de l'abbaye de St-Mathieu, elle a connu très tôt l'agriculture mais a surtout vécu de la mer grâce à son petit port de pêche bien abrité et à ses marins de commerce qui ont navigué sur toutes les mers du monde. When an English liner sank in 1896 in the Fromveur Current, its inhabitants rescued the survivors and earned England's recognition for the care they had given to the many bodies washed up on their coast. Knowing their shortage of fresh water, Queen Victoria offered them a cistern fed by an impluvium.
In 2024, there are 164 Molénais living on an island of 0.75 km2.

Lampaul-Plouarzel owes its name to Saint Pol-Aurélien, a Welsh monk who later became bishop of Leon, who would have landed on Armoric shores in the VIe century and founded a monastery later destroyed by the Vikings. Thanks to its naturally sheltered port, Lampaul-Plouarzel has always used gabarres to carry out a cabotage trade. Today, it's a commune of 2,153 inhabitants, the most densely populated in the Pays d'Iroise, with an area of just 4 km2.

Lampaul-Plouarzel, a coastal town with a natural port, has seen Mediterranean ships pass through since ancient times. In 1959, a massaliote gold coin from the IVe century BC was found among the seaweeds on its shore. It could have come from the Pythéas expedition. See the document, column opposite. Like Lampaul-Plouarzel above and Lampaul in Ouessant, the town owes its name to the monk Saint Pol-Aurélien who built a monastery in the VIe century on the site of the current church. The territory became a parish in its own right in the Middle Ages, after being a Ploudalmézeau parish part. Mainly farmers, the Lampolais population numbered 825 in 2024, covering an area of 6 km2.

  A mainly agricultural commune, Landunvez has a population of 1,518 in 2024, covering an area of 13.5 km2.
Although its main activity is focused on cattle and pig farming, the commune has an old castle and a magnificent coastline, a real jewel of the Iroise Country, which is well known by hikers and water sports enthusiasts alike. On stormy days, the curious who love thrills flock to the spectacle of a wild coast assaulted by the waves. Every summer, commented walks, a sea festival and concerts are organised for an audience increasingly attached to its charm.

With a well sheltered estuary port, Lanildut has always been oriented towards the sea. Its name comes from that of Saint Ildut, who, in the Ve century, founded a hermitage near the shore. Many small shipowners, or boat owners, have had their beautiful homes built in the parish. Very active, the port of Lanildut has specialised in the harvesting of seaweed near the Molène archipelago. It has thus become the leading seaweeds port in Europe and supplies several plants producing gelling agents for food or cosmetics. In 2024, the commune has 962 inhabitants on its 5.8 km2 site.

   Home to the Communauté de Communes du Pays d'Iroise (Pays d'Iroise Community of Communes), Lanrivoaré is a 15 km2 agricultural commune close to St-Renan, with a population of 1,512. Here a legend places the martyrdom of 7777 saints during the Ve century. Lan Rivoaré ( the monastery of Rivoaré) comes from the name of a hermit whose life could be linked to this legend, probably remembering a later massacre of the population during the Viking incursion of 919.

Le Conquet

  Already in the Middle Ages, man did not say the village but the town of Le Conquet. Occupied since prehistoric times, this port at the end of the world was a shelter on maritime routes and a nest of commercial ships owners. The Normans and then the English devastated him several times. Inland, the village of Lochrist still bears witness to the time when, simply as a part in the parish of Plougonvelin, the historic centre of Le Conquet was located away from the sea. As demographic pressure changed, the Lochrist church was dismantled stone by stone in 1856 to be transferred to its present location.
This is how Anatole Le Braz described Le Conquet in his book Le gardien du feu written in 1899 :
  Le Conquet, the pearl of Breton ports, a veritable marine hive, buzzing like a conch, with its terraced quays, the four hundred sails of its fishing fleet, its almost seigneurial houses, built in the opulent ages of the buccaneers, its noisy and colourful population, a mixture of all the types and bloods of Brittany.
  Today, it's still a bustling little town with a population of 2,799 in 2024. Active because of its pretty fishing port, mainly oriented towards crustaceans : edible crabs, lobsters and rock lobsters. But also because of tourism : the old boatsmen's houses, the ria populated by birds, the pier for the islands, the Iroise Marine Natural Park, the long Blancs Sablons beach, the magnificent coastal paths attract a large public. The commune, which owns the Kermorvan peninsula and eight islands of the Molène archipelago, now extends over 8.5 km2.

This former Plouzané parish part has been occupied by humans since prehistoric times, as shown by the old Kereven alignment. Many Christianized Gallic stelae show that this occupation has continued. Having become a commune during the French Revolution, its former name of Locmaria-Lanvénec was changed, but its 5138 inhabitants are still known as Lanvénecois. It was from its shore that the first French transatlantic cable was launched in 1869. Nearborough of Brest, this 23 km2 commune is still essentially agricultural but is rapidly becoming urbanized and industrialized.

  Milizac was and still is mainly oriented towards agriculture. Its vast territory of 33 km2 is mainly dedicated to cattle and pig breeding as well as potato cultivation. The commune was once the seat of several chatellenies, including the Curru manor house. There are also several water mills and three dovecotes. The new commune of Milizac-Guipronvel, with its 4,649 inhabitants in 2024, is currently in the midst of an urbanization phase thanks to its proximity to Brest.

Guipronvel was an agricultural commune that took its name from that of Saint Ronvel whose hermitage, dating back to the VIe century, would have been located in the Coat-Douen woods. First the centre of a large religious district that once encompassed six parishes, Guipronvel became a simple part of the Milizac parish, its neighbour. Then it was autonomous since the Revolution until 2017.
In 2016, it decided to merge with its neighbour Milizac.It had 787 inhabitants in 2014 on its 8.4 km2.
Its heritage, painstakingly listed by Jean Lescop, a native of Guipronvel, is described in detail and illustrated with numerous photos on the communal website.

"War vor ha war zouar" =  On sea and land

The largest municipality in the Pays d'Iroise, with its 43 km2, boasts the highest menhir in Europe on its territory, thus proving the seniority of its human occupation. The name Plouarzel comes from the name of Saint Arzel, a Welsh monk who came to found the parish in the VIe century. At the end of the Middle Ages, Hervé de Porsmoguer, a brilliant captain from Plouarzel, whose motto became that of the town, distinguished himself in front of Pointe St-Mathieu in a naval battle against the English. He sacrificed his brand new warship and his entire crew in order to sink the enemy flagship.
Knowing a brilliant development thanks to the culture of the wheat and the flax, Plouarzel did not disdain either, from the middle of the XIXth century, the harvest of the seaweed which was burned on the coast to provide bread of soda to the factories of the coast.
In 2024, this farming community of 3,942 inhabitants will be home to the CROSS at the tip of Corsen, monitoring and safeguarding the intense naval traffic from the Cotentin peninsula to the tip of Penmarc'h.

It is a bipolar urban area, of 23 km2, with a centre of more than 4000 inhabitants in the countryside and a coastline, Portsall ( = the port of Trémazan castle ), of 2000 residents, four kilometres away. But all in all, Ploudalmézeau, the second-largest commune in the CCPI with 6347 inhabitants, was settled very early on, with megaliths dating back 6,000 years. A huge parish originally encompassing four other communes, it transferred its church to its current location in the Middle Ages. It was then dismembered and its mayor guillotined during the Revolution for collusion with the enemy. The town was severely affected in 1978 by the stranding of the tanker Amoco Cadiz in front of Portsall, but fought hard against the gigantic pollution that followed. Its mayor, Alphonse Arzel, then took the lead in a coalition of plaintiff municipalities and finally succeeded to do convicting the polluter 14 years later in the American courts.

Today, this 18 km2 seaside resort has a population of 4,410. Its location between Pointe St-Mathieu and the Brest Channel has always given it strategic importance and traces of human occupation date back to the Mesolithic period. A Bronze Age necropolis with burials in stone chests has recently been discovered on the Bertheaume plateau, probably indicating the presence of a village 4000 years ago. Later, a Roman road was to join Carhaix ( Vorgium ) to St-Mathieu (Gesocribate ? ). The struggle against England led to several bloody naval battles in the 16th century in front of its coasts and a devastating landing. The parish, which was depending on the powerful abbey of St-Mathieu, saw Lochrist and Le Conquet detach from it during the Revolution. Today, Plougonvelin is focusing on tourism, which is developing around its beautiful beach of Trez Hir and Pointe St-Mathieu.

Roman remains testify to the age of human occupation in the territory of this large municipality of 39 km2 which has nevertheless been amputated from its islands and the Kermorvan peninsula for the benefit of the Conquet. Comprising two separate parishes, since it includes Lamber, this rural commune of 2120 inhabitants is essentially focused on livestock breeding and agricultural production. Its population has been growing by 6.1% since 2013.Its coastline of coves and cliffs, its lookout on the highest hill in the Pays d'Iroise, however, is gradually seeing a growth in hiking tourism.

The two great menhirs of Kergadiou show that man has occupied this territory since the Neolithic period. The parish is said to have been founded in the 6th century by Saint Budoc, whose reliquary of the church has three fingers perilously brought back from Dol by his disciple Saint Ildut. It was one of the most extensive in the Leon, but has been amputated from Larret, Lanildut, Porspoder and Landunvez. Covering an area of 25 km2, this agricultural commune has a population of 1258.

As shown in the list opposite, Porspoder is the capital of the megaliths of the Iroise country. But not only that: this former Plourin parish part, which became a parish in the 17th century, has a superb coastline that always attracks walkers. The lap around the St. Lawrence Peninsula is one of the most beautiful discoveries in the region. The municipality thus combines the advantages of the countryside and the sea. And if it has lost the port of Aber to Lanildut, it has managed to maintain the originality of the port of Mazou and benefited from the attachment of the former commune of Larret, two charming places that delight tourists. The commune has a population of 1,758 over an area of 11 km2.

   The main city of the entire CCPI territory, St-Renan was from the Gallo-Roman era a place where cassiterite, the tin ore, deposits were mined. In the Ve century the Irish hermit Ronan founded his first hermitage there. An important medieval center with a court of justice, the town, with 8358 inhabitants and a surface area of 13 km2, has become a very active historical, commercial and cultural center. Once mainly oriented towards livestock, its weekly Saturday morning market still attracts a considerable public at the foot of medieval houses. Thanks to its central position in the Iroise Country, its proximity to Brest, its vast bodies of water, the city, in full expansion, is experiencing a dynamism that many others envy it.

The name of this small neighbouring commune of Le Conquet comes from that of Saint Tugdual, also known as Saint Pabu. This Welsh monk who came to evangelize the Armorican country would have established his first monastery there as early as the Ve century. Focused on livestock and agricultural production, Trébabu, which covers just 4 km2, is developing its housing estates in order to significantly increase its population, which stands at just 361. Its church, nestled in the hollow of a romantic valley, and its Notre-Dame du Val chapel, whose main statue has recently undergone an astonishing peregrination, are worth a visit.

This small commune of 6 km2, located at a good distance from the coast, is naturally rural. It has been occupied at least since Gallic times, as shown by the stelae that still remain. Ancient parish part of Plouguin, its name comes from that of Saint Gouescat, also named Saint Ergat, patron saint of the parish, to whom is dedicated, in the woods, a sacred fountain. Several small manors and remarkable houses testify to its past importance. During the Second World War, it hid an important maquis. Every year in May, the 327 inhabitants of Tréouergat organize a major horse festival that attracts equestrian enthusiasts from all over the département.
