Imagine massive granite walls reflecting in calm waters and surrounded by emerald lawns. The moats of the Castle of the Dukes of Brittany (Douves du Château) are a picturesque system of fortifications located in the heart of Nantes. This historic site combines the austerity of a medieval fortress with the elegance of a park, creating an ideal setting for a stroll.

As an important part of the defensive system in France, these moats stretch for 500 meters along the walls, which feature seven majestic towers. The contrast between the gray stone of the outer fortifications and the white tuff of the castle's inner buildings highlights the uniqueness of the architecture, which blends Gothic style with Renaissance elements. This site serves as a living testament to the region's rich history and its strategic role in the past.
Today, the moats are an open public space of the historical_place category, where locals and tourists can escape the city bustle. Since 1915, the castle has belonged to the city and serves as home to a history museum, while its well-kept moats have become one of the most recognizable photo spots, offering magnificent views of the ancient bastions and the old town.
