The Château du Taureau stands as a striking fortress on a small islet in the Bay of Morlaix, Finistère. With a history spanning over four centuries, this remarkable structure has undergone numerous transformations, serving various roles throughout its existence. Initially built as a defensive fort, it later became a state prison, a private retreat, a sailing school, and now a historic monument open to the public.

The Origins of Château du Taureau

The construction of Château du Taureau began in 1542 in response to a growing threat. Two decades earlier, in 1522, English forces had advanced up the Dossen River, reaching the heart of the Morlaix estuary. The town suffered looting, but the resilience of its inhabitants ensured its survival. Determined to prevent future invasions, the people of Morlaix financed and built a fort at the estuary’s entrance. This initial structure, known as Fort du Taureau, was relatively modest, with walls standing only 6.5 meters high—half of what they would later become.

During the reign of Louis XIII, the fort’s governorship became a coveted title among the Morlaisians, often leading to disputes. However, in 1661, under the rule of Louis XIV, the French crown claimed ownership of the fort, transforming it into state property. The king converted it into a military garrison and prison, reinforcing its strategic importance. Given Brittany’s geographic proximity to England, the region played a crucial role in European military conflicts.

Vauban’s Influence and the Fort’s Reconstruction

Recognizing the need for a stronger defense, the renowned military engineer Vauban inspected the site in 1680 and ordered extensive renovations. The original fort was almost entirely rebuilt, with only the French Tower remaining unchanged. The new structure was designed for resilience, using granite from the nearby island of Callot.

The redesigned fortress took on an oblong shape to conform to the rocky islet’s natural contours. Measuring 60 meters in length and 12 meters in width, with walls rising to 12 meters, the fort covered a total area of 1,450 square meters. Inside, it housed eleven casemates, each capable of holding a cannon. Additionally, the fort included living quarters for soldiers and officers, two dungeons, a kitchen and canteen, a chapel, and latrines.

Transformation into a Prison and Decline

Despite its military purpose, the Château du Taureau saw its role shift as Morlaix’s economic fortunes declined. By 1721, it was repurposed as a prison, a function it would serve for over 150 years. One of its most notable prisoners was the revolutionary Louis Auguste Blanqui, a prominent figure of the Paris Commune, who was confined there in 1871.

By 1890, the fort had lost its military significance and was officially disarmed. In 1914, it was designated a historic monument, ensuring its preservation under state protection. However, the 20th century brought further transformations. In the summer of 1930, the Vilmorin family rented the castle as a private vacation retreat, enjoying its secluded and picturesque setting until 1937.

A New Chapter: Sailing School and Abandonment

In the 1960s, Château du Taureau found a new purpose as a sailing school. For two decades, aspiring sailors trained within its historic walls, making use of the bay’s unique conditions. However, by 1982, the school ceased operations, and the fortress was left to deteriorate.

By the late 20th century, the once-mighty fort had fallen into a severe state of disrepair. Recognizing its historical and cultural importance, local and national organizations launched a major restoration effort in 1998. After six years of meticulous work, the Château du Taureau reopened to the public in 2004, allowing visitors to explore its storied halls and experience its remarkable past.
