The construction of Port Mulon Castle dates back to the 19th century. Of its various owners, it primarily preserves the memory of Prosper Coinquet. Born in 1825 in Nantes, Prosper Coinquet was mayor of Nort-sur-Erdre twice, from 1859 to 1874, and again from 1877 to 1892. He was also a general councilor for the Loire-Inférieure department from 1883 to 1887. This lawyer by training was also a great lover of the arts. He was himself a musician and poet. He composed numerous songs and waltzes that enjoyed considerable regional success. He dedicated one of his waltzes, simply titled "Le port Mulon," to his castle. Prosper Coinquet chaired or was a member of several musical and literary societies. It was therefore only natural that he decided to make the château the setting for evenings dedicated to the arts. Readings and concerts were held in the park or in the reception hall. Nantes artists invited to perform came by way of the Erdre River. The setting, its tranquil riverbank, and its magnificent park wooded with rare species, thus retain the imprint of the music that was performed there until 1892. That year, Prosper Coinquet died at home. Since 2006, music has once again resonated in the park's foliage. Indeed, at the end of June, the venue hosts the La Nuit de L'Erdre festival. Today, the Château de Port Mulon and its park are managed by the municipality of Nort-sur-Erdre. A reception hall can be rented from the town hall, whether for private or professional events. You can also take yoga classes at the château. As for the Nantes Atlantique improvisation league, it has made it its headquarters. Finally, since 2017, the place has become a coworking space whose success continues unabated. As for the park, it's a place where, in addition to enjoying its vast spaces and magnificent trees, you can indulge in an orienteering course. Twenty markers are scattered throughout, and by exploring them, you'll learn much more about the treasures it contains. During your stroll, you'll undoubtedly encounter riders who enjoy riding their horses there. And if, at nightfall, you spot the fluttering shadows of numerous bats, don't be surprised. For several years, the castle and grounds have been havens for these nocturnal animals.

The greenway project along the former railway line is the subject of much debate... and it's not about to stop! Ninety people attended the meeting organized by the municipality and the Erdre & Gesvres Community of Communes (CCEG) on Tuesday, April 15, 2025, at the Simone-de-Beauvoir Hall, regarding the development of the former railway line. For some participants, the greenway seems a long way off, as the road before construction begins. The will to implement this ambitious 26-km project is there, however. The users are numerous: walkers, hikers, people with reduced mobility, cyclists, mountain bikers, horseback riders (with or without a horse-drawn carriage), runners, farmers, heritage enthusiasts, hunters, local residents, rollerbladers, and simple strollers (with or without a stroller). Between Treillières and La Chapelle-sur-Erdre, commuters also use the road to get to work. It's not easy to accommodate all these people. Sylvain Lefeuvre, Vice President of the CCEG, in charge of mobility, recounted the discussions exchanged with partners in 2023: "We want to avoid conflicts of use. For our consultation, 881 responses were received, including 300 in Treillières. The population participated well," conceded the elected representative of Nort-sur-Erdre. "There is no procurement issue. Of the seventeen million allocated to the project, the State is granting us nine over six years. Its services will give the green light, but we won't be able to complete the project piecemeal. It will be all or nothing." Wilfried Braud, head of the Erdre & Gesvres mobility department, noted the participants' concerns about the quality of the road surface: "We need to find a sustainable solution that doesn't require major maintenance every ten years." A hard asphalt surface with a softer lane alongside seems to be the solution. There are also dual-lane lanes with grass in the middle. Local residents want this road to be off-limits to motorized vehicles and are wary of quads and dirt bikes. "We don't want boulevards," asserts this regular user of the promenade. Questions are being asked of the technical services. Studies are needed to regulate water management. Access for the fire department needs to be provided. What about the ancillary services, restrooms, the water point, and the rest area? And what about the heritage? The Fay-de-Bretagne shelter has been perfectly restored. Will the same be true for the one located opposite Treillières station? Users are aware of the lengthy process involved in a community project. They understand: patience is required for this greenway.
