The Château de Brest (, ) or Castle of Brest is a castle in Brest, Finistère, Brittany, France. The oldest monument in the town, it is located at the mouth of the river Penfeld at the heart of the roadstead of Brest, one of the largest roadsteads in the world. From the Roman castellum to Vauban's citadel, the site has over 1700 years of history, holding right up to the present day its original role as a military fortress and a strategic location of the highest importance. It is thus the oldest castle in the world still in use, and was classified as a monument historique on 21 March 1923.
The structure's heterogeneous architecture has been the result of continual adaptations to developments in siege warfare and armament on land and sea. The château stands on the opposite bank to the Tour Tanguy combining to defend the entrance to the Penfeld.
An ideal geographic location
The Roadstead of Brest, well-protected by a narrow "goulet" but sufficiently large to allow ships to turn or move, forms a natural harbour. Its dimensions make it a small inland sea, capable of receiving the largest fleets. It is so vast that it offers a protected haven for ships.
This natural haven is fed from the north by the Penfeld River, which flows down from the plateaus of Léon. Its lower course winds through the landscape, its high, sheltered banks providing protection from strong winds. The broad and sheltered waters are deep enough to accommodate even large-tonnage vessels safely.
The cape separating the roadstead from the bay forms a naturally fortified site: three of its four sides are protected by the surrounding terrain, while only the fourth requires additional fortification, and even there, the position is relatively easy to defend. This exceptional combination of natural protection and strategic access gives the castle immense military and strategic significance.
The castle was thus built on a rocky outcrop which the river has carved out of the cliff at its mouth in the estuary. Since the place overlooks and dominates the sea, it controls access to the Penfeld and the lower reaches of the Élorn towards Landerneau, all whilst overlooking a major part of the roadstead and its entrance: the Goulet de Brest.
History
Origins The site was inhabited during the Lower Palaeolithic (300,000 BC) and in the Neolithic agricultural activity occurred on the site. Other coastal populations are known in the 6th and 4th centuries BC and the rocky spur was occupied until the end of the Iron Age. Its remarkable position allows a hypothesis that the site held a prehistoric fortification, but the first fort of which evidence remains is from the Roman era.
Around 500 BC, a tribe of merchants and sailors in leather barks known as the Osismii peopled the region. To them are to be attributed the gold coinage discovered around Brest, as well as a road predating the Roman presence in the area. The tribe's territory (roughly equivalent to today's Finistère) was bordered to the south by the territory of the Veneti and to the east by that of the Curiosolites, with its capital at Vorgium (Carhaix). This end of the world (Finis terrae) only saw Roman occupation very late in the Roman period.
Roman era
From Roman coinage found on the site, it appears that the Romans were present there at least by the reign of the emperor Septimius Severus (193–211). The Roman province of Armorica thus had to face Saxon raids. To face the threat of invasion and the disintegration of the Roman empire, it became necessary to create forts at Brest and several other sites along these coasts.
The Romans erected a defensive work at the end of the 3rd century. This camp or castellum housed 1000 men of a troop, headed by a prefect, as well as a fleet designed to intercept pirate ships. Only one of its walls now survives - these foundations were encased in the ramparts of the present castle, extending for 120-140m in length, on an average height of 3-4m.
These begin from the base of the wall. In large part interred under the false-wall of the castle or under the carpark, it remains visible at 2-3m high. Their external appearance is characteristically Roman, with brick and stone alternating in "opus mixtum", sometimes arranged in "fish-bone" pattern. This 4m thick fortified wall, with 10 cylindrical towers, defends the point and forms a bar across the spur.The absence of Roman remains inside the castle suggests it was a purely military work and not also a civil oppidum. The section of the razed towers at ground level remains visible in the false wall.
It seems that the Romans did not entirely complete the fortified wall since their presence here was short-lived. At this era, it is possible that the sea coast was simply defended by a ditch and palisade. 1832 saw the discovery of the foundations of a round tower, Roman in appearance, near what is now the tour de Brest.
The wall was certainly completed as a curtain wall on 3 sides, in a regular trapezoid, with 12 turrets on each side. Another Gallo-Roman remain survives - a 1.4m wide postern, demolished in the Middle Ages (its stones and bricks survive in the tour Madeleine).
Ancient Brest was probably the site known to the Romans as Gesoscribate at the termination point of one of the Armorican roads.
The counts of Léon From the Romans' departure (410–420) until the 11th century, little is known as to the history of the castellum at Brest. It remained a stronghold and thus belonged to the counts of Léon, whilst a town developed at the foot of the Roman enclosure. In 537, count Elven held court at Brest. His daughter, Azenor, is the subject of a legend and she has thus given her name to one of the castle's towers.
Around 1064 or 1065, duke Conan II (or possibly Léon Morvan II, one of the vicomtes de Léon) ordered the renovation of the castle, cutting a moat around it and building a chapel within the enclosure, dedicated to "Notre Dame de Pitié" (destroyed in 1819), and a keep (perhaps in the northern corner of the fortifications).
In 1240, the castle passed to the duke of Brittany, John I, and became an essential part of the duchy's defence system. Hervé IV left the place, HQ of the counts of Léon, to avoid a confrontation and in return for 100 livres of rent. The loss of the castle and attempts to retake it sounded the death knell of the county of Léon.
The castle remained unbeaten by the Normans. During this period was built the tour César, possibly on the ruins of a Gallo-Roman tower. It blocked all access to the rocky outcrop. The tour Azenor and the curtain wall onto which it is built also date to this time.
The dukes of Brittany
The 'burg' expanded and left the castle. One of the two earliest burgs was situated beside Recouvrance (right bank) at the foot of what is now called the Tour Tanguy, and the other, larger and more enclosed one in front of the castle (left bank).
In return for services rendered, Philip IV of France made John II a peer, but his son John III's death led to a 22-year war of succession in the dukedom. In 1341, John, count of Montfort, half-brother of John III, fought Charles de Blois (husband of Jeanne de Penthièvre) for the dukedom. It was vital for John to capture Brest's castle, to prevent it becoming a refuge for his enemies or a landing-point for his enemies' ally Edward III of England. To make certain his siege would be successful, he ensured he had a large numerical superiority and powerful siege engines to batter a breach in the walls, but even so the assault lasted several days. The castle's captain Garnier de Clisson was killed in a counter-attack when he was trapped outside the walls by the closed portcullis, and so the defenders surrendered on the condition that their lives would be spared. This was the last time the castle would be taken by force. John of Montfort restored the buildings he had damaged in the siege and added to the defences, putting in place a garrison under Tanguy du Chastel, who built Brest's first enclosure.
On 7 September, the court of peers decided in favour of Charles de Blois's right to the duchy, and at the end of the year John of Montfort was imprisoned in the Louvre. His wife Jeanne of Flanders returned to the castle to shelter within its walls and sent an emissary to Edward III to seek an alliance. Thus the English set up a base in the castle thanks to the political disorders of August 1342, giving them control of the maritime route used by their trading ships and military convoys from 1342 to 1397. William of Rohan, earl of Northampton, headed the base with the title of lieutenant-general of Brittany, and Edward rejoined them in Brest 2 months later to support the rights of Montfort.
The Treaty of Guérande of 12 April 1365 concluded that women could only lay claim to the duchy of Brittany should there be no legitimate male heirs to the House of Brittany. John of Montfort rendered homage to Charles V of France and so Edward III no longer had any reason to continue his military presence at the castle. However, the place was too important to give up and Montfort was still financially dependent on England. Thus Charles V let Montfort off participating in the war he then launched on Edward III, but Montfort played a double game and passed a treaty on 21 February 1372 to open his lands to English troops even though constable Du Guesclin and Clisson were marching from Brittany against him, and the Breton commune of Concarneau was captured.
In the spring, the Breton lords seized the duchy's principal lands, denouncing their overlord, siding with the French king, rallying around the viscount of Rohan and charging Du Guesclin with hunting down the English. Montfort fled Brest for England on 28 April 1373 and the constable won victory after victory, retaking Concarneau and finally ending up before the walls of Brest castle in August. Command of English forces in the east had been entrusted to Sir John Neville under the authority of lieutenant-general Robert Knowles, with Brest's garrison under the famous English captains Robert Kermoulés and Fenville. After three weeks of siege Du Guesclin concluded a 6-week truce to begin on 6 July. At the end of that period, Kermoulés promised to hand Brest castle over to the besiegers' if no other help reached its defenders by then and under the condition that the place could not be re-supplied. The constable left the siege under the command of Olivier de Clisson to rejoin the duke of Anjou at the siege of the Castle of Derval (château de Derval). Clisson used the truce period to build the fort du Conquet. On 2 August, the English fleet under Salisbury (who also took over command of the castle) disembarked supplies and reinforcements which definitively rendered the castle impregnable.
The Treaty of Bruges of 27 June 1375 marked an armistice between France and England, and officially handed Brest's castle over to John of Montfort, though the town remained under English protection and Montfort was forced to return to England that September. In 1378 the Duke of Montfort was declared Duke of Brittany under the name John IV. He pursued Jean de Blois, with Charles V of France taking his side. John IV thus sought help from England and passed a new treaty, handing the castle over to Richard II of England. The English disembarked reinforcements on 15 June and fought off an attack on the castle by French royal troops under the viscount of Rohan and including the lords of Laval, Léon, Clisson and Beaumanoir.
