The best running trails around Montaigu

. Originally, there was an ovoid-shaped enclosure flanked by about ten towers and a gatehouse, located to the northeast. The fortified town was located to the north of the fortress and extended a little to the east. A dry moat separated the fortified town from the fortress. A barbican protected the gatehouse. A Romanesque keep of the Niort type, with its courtyard and small enclosure, was located in the castle courtyard, roughly in the middle in the north-south direction and located to the west. The fortified city extended from the rue de Gaulle, a gate was located at the level of the Carré de l'Europe (the porte de Nantes), then the ramparts continued along the rue de la Place du Champ de Foire, then went back down the Esplanade des Olivettes, where a gate was located towards the roundabout of the rue des Jardins (porte de Tiffauges) then the ramparts ran along the Asson to go up the rue du Pont Jarlet and around the barbican not far from the Presbytery The dry moats surrounding the city were 16 meters deep in the 15th century, today they are flowered and are the subject of different colored squares decorating this part of the ramparts.

In the 9th century, a castrum, a wooden castle built on a mound of earth, was built to counter the Viking raids that had previously sacked the city of Durivum (Saint-Georges-de-Montaigu). For strategic reasons, this fortress was built on a rocky spur at the junction between the Maine and Asson rivers. Maurice I of Montaigu, the first known lord, witnessed the consecration of the church of Saint-Nicolas de la Chaize-le-Vicomte in 1099. His successor until 1174 was Brient I of Commequiers, married to his daughter, Agathe de Montaigu. Later, his grandchildren, Brient II, Maurice II "the Younger," and Marguerite, succeeded him. It was perhaps this Brient II who had the Romanesque keep built in 1218, a large square tower with flat corner towers. He also removed the wooden palisade, replacing it with a wide moat extending to the Saint-Georges Gate. The Montagues (also known as Belleville by marriage around 1180) pledged allegiance to the Plantagenets, Henry II, Richard the Lionheart, and John Lackland. Margaret of Belleville-Montaigu, daughter of Brient de Montaigu and Agnes de Belleville, granddaughter of Maurice I de Montaigu, sister of Maurice II de Belleville-Montaigu, married Hugh of Thouars in 1203. In 1227, the couple submitted to Philip Augustus through the ceremony of homage. Hugh of Thouars died in 1229, and Margaret remarried in 1235 to the Duke of Brittany, Mauclerc, whose real name was Pierre de Dreux. Marguerite de Montaigu died in 1241, childless. The lordship of Montaigu fell to her nephew, Maurice III de Belleville-Montaigu (d. c. 1297; son of Maurice II). He became lord of Montaigu upon the death of Mauclerc in 1250[2], and his son Maurice IV (d. c. 1292) ensured the succession through his children Jeanne (d. 1284 Geoffroy II David de La Flocellière) and Maurice V de Belleville-Montaigu (he married 1° Sibylle, daughter of Geoffroy VI de Châteaubriant, then 2° Isabelle/Létice de Parthenay, daughter of Guillaume V Larchevêque de Parthenay). Jeanne de Belleville (c. 1300-c. 1359), daughter of Maurice V of Montaigu and Létice of Parthenay, married Olivier IV of Clisson for the second time in 1328. Olivier IV was executed by beheading after being suspected of "felony" against the English, during the Hundred Years' War. Jeanne became a privateer with her children Olivier V and Jeanne de Clisson, in revenge, and was banished from the kingdom of France. While she attacked French ships, the fortress of Montaigu was held by the English, according to the Treaty of Brétigny-Calais, a garrison of which engaged in pillaging the surrounding area. Jeanne lost her ship and withdrew with her children to England. Olivier V, having grown up, rallied to the king of France, recovered his property in 1362 and fought the English with Bertrand du Guesclin. In 1373, Olivier and Bertrand succeeded in driving the English out of Montaigu, and Olivier ceded the lordship to his sister Jeanne, who had married an English captain, Jean Harpedenne. The latter sided with the King of France in 1373 and became Jean de Belleville. His grandson, Jean III, married Charles VII's half-sister, Marguerite de Valois, in 1433. Louis I de Belleville succeeded Jean III. King Louis XI advised him to fortify the town between 1464 and 1468 to protect it from the Bretons.

From the small garden at the foot of the ramparts, a lovely view of the remains of the medieval castle of Montaigu.

This rocky spur was fortified in the 9th century to fight against Viking invasions. In the 15th century, the entire medieval town was protected by ramparts, this time against the Bretons. The remains still visible today give an idea of the importance of this fortified castle at the time.

The most visible part of the remaining remains of the fortified castle, the remains of which can be found here and there in the city.

At least what remains of it ... Remains of a seigneurial estate with the ruins of a 14th century castle, of which only the moat and two towers remain. The layout of the surrounding buildings is also reminiscent of the estate.
