Tour du Bourg
FortressHidden Treasure
A medieval sentinel in the heart of Saumur, the Tour du Bourg reveals the military architecture of the 14th and 15th centuries, a precious vestige of a fortified complex that has been listed as a Historic Monument since 1972.
History
Set within the urban fabric of Saumur, a town whose destiny was intimately linked to the great hours of the Loire and Anjou, the Tour du Bourg stands out as one of the most authentic witnesses to the medieval defence of the Loire Valley. Far from the romantic reconstructions of the 19th century, it offers those who can observe it a direct dialogue with the raw stone of the builders of the Middle Ages, in a region better known for its castles of pleasure than for its warlike structures. What makes the Tour du Bourg so special is first and foremost its remarkable survival in a town that, like so many other towns in the Loire region, has suffered the ravages of time, the Wars of Religion and the great urban transformations of the 18th and 19th centuries. As part of a larger fortified complex, it was once one of the key elements in the medieval town's defensive system, ensuring that access to the town was guarded and that its inhabitants and goods were kept under control. The experience of the visit is a welcome one of simplicity: here, there are no large furnished flats or formal gardens, but the very stuff of history, the local tufa stone quarrymen have been extracting since the early Middle Ages, and whose luminous whiteness characterises the architecture of the whole region. This soft, easy-to-cut stone enabled medieval masons to achieve remarkable precision in the defensive details - archways, machicolation corbels, corner quoins - all of which deserve careful observation. The Saumur setting further enhances the interest of the site: just a stone's throw away flows the Loire, a royal river and an axis of civilisation, while Saumur castle, perched on its rocky spur, is a reminder that this town was one of the major strategic challenges of medieval Anjou. The Tour du Bourg is a natural addition to this exceptional heritage site, offering a complementary and less-frequented insight into the region's military architecture.
Architecture
The Tour du Bourg belongs to the large family of medieval defensive and surveillance towers that were characteristic of Anjou's military architecture in the 14th and 15th centuries. Built of Loire tuffeau - the easy-to-work, white limestone that is the geological signature of all Loire architecture - its meticulous construction reflects the skills of the quarrymen and masons of Anjou, whose reputation extended beyond the borders of the province. The plan, which was probably quadrangular or slightly trapezoidal like many towers of this generation, allowed for effective surveillance of the surrounding traffic routes, while at the same time enabling the interior to be organised into superimposed levels linked by a stone screw. The defensive features characteristic of the period can be seen in the facings: recessed archways, cross-shaped loopholes for oblique fire, and the probable corbels of the machicolations corbelled into the upper levels. The large ashlar quoins at the corners ensure the solidity of the joins, while the regular courses bear witness to a well-thought-out, long-lasting project. The thickness of the walls, which was substantial enough to withstand the projectiles fired by the siege engines and then the incipient artillery, is one of the distinctive features of this work. As part of a larger fortified complex, of which only fragments remain, the Tour du Bourg was originally linked to the curtain walls linking other works in the urban defensive perimeter. This overall logic, which is difficult to read in today's urban fabric, is nonetheless perceptible to the trained eye, who can see traces of the vanished wall in the topography of the streets and plots.
