In the south, the Oust forms Guillac’s municipal boundary for around nine kilometres. The nautical stop is located on the Nantes–Brest Canal. Guillac also has several sites of cultural and historical interest, offering insights into different periods and themes. When planning your trip, you can choose between two distinct focuses: waterways and local history.

Waterways along the Nantes–Brest Canal

The nautical stop has a boat pontoon and a rest area with benches and picnic tables. From here, you can access walking and cycling routes, including the Vélodyssée. If you’d like to combine a break by the canal with a walk or bike ride, the rest area is a convenient starting point. As some facilities may change, check their current condition before your visit.

A heritage trail starting in the town centre

For a heritage-focused visit, the 6-kilometre Circuit d’interprétation du patrimoine de Guillac takes you through the heritage and history of the commune. It starts at Église Saint-Bertin in the town centre. The church is both a practical landmark for the route and a historic building in its own right.

Église Saint-Bertin was built in the first half of the 16th century. Originally, it consisted of a single nave and a northern side chapel. The chapel’s tracery windows feature flamboyant Gothic forms. Inside, you can also see the 17th-century oil painting La Donation du Rosaire. The church thus brings together its original layout and window design with a later work of art.

Fountains, abbey and memorials

Fontaine Saint-Bertin was built in 1665 for the de Saint-Pern family. A stone statue of Saint Bertin has stood in a niche in the fountain since 1927. The fountain’s construction date and the date associated with the statue mark two distinct points in the history of this place.

Abbaye de Saint-Jean-des-Prés was founded in the mid-12th century under the Rule of Saint Augustine. Its buildings were rebuilt between 1663 and 1682. The medieval foundation and the 17th-century rebuilding represent different phases in its history. Some parts of the abbey are classified as French historic monuments, while others are listed; the site is partially protected.

The Colonne des Trente is another memorial landmark: the 13-metre granite obelisk has stood above a former battlefield since 1823. Its commemorative inscription names the thirty Breton fighters. The inscription and the connection to the former battlefield give the obelisk a different character from the buildings and works of art in the town.

For planning your outing, there is a practical difference in what each option offers: the stop provides access to walking and cycling routes, while the 6-kilometre Circuit is a named trail that starts at the church and focuses on Guillac’s history. You can decide whether waterways and outdoor activities or heritage should be the focus of your time in Guillac.
