As part of Heritage Days, Isabelle Favre, owner of the La Roche Thévenin estate, opened her property to the public. She allowed visitors to discover both the exterior and interior of her residence. "Traces of this ancient 5,000-hectare barony can be found as early as 1411," explains Isabelle Favre. This fiefdom was then called La Roche Brisard, after its former lords. It was in 1515 that it became the property of the Thévenins, one of the most notable and oldest families in the Barony of Montaigu. Nine generations of Thévenins have succeeded one another. The Château de La Roche Thévenin burned during the Revolution. The plane trees, cedars, and magnolias date from that time, in 1887, when the Abbot of Meslay purchased this house for sick priests. Another owner of the property is the sculptor Grootaers, who is responsible for the fountain in the Place Royale in Nantes and some of his sculptures, which led to the estate being listed as a Historic Monument. Isabelle Favre and her husband purchased this property in 1984. But their love at first sight quickly turned into a nightmare: the building, hidden by lush vegetation, required extensive renovations. Twenty-eight years of work revealed, beneath the cement slabs, terracotta mosaics, a granite staircase with arrow slits, the Thévenin coat of arms on a doorframe, and a Stations of the Cross hidden in a chapel converted into a hayloft.

Located east of the Parc des Remparts, the first part of the Val d'Asson Park opened in September 2020. The second part will open in July 2023. In total, it covers 5 hectares of greenery in the heart of the city. Located in the city center, parking is available at Place de l'Hôtel-de-Ville or Rue du Pont-Jarlet. Admission is free and the park is open year-round. The various paths and footbridges are accessible to people with reduced mobility. The 5 hectares of parkland connect the city center with the Hauts de Montaigu district. Crossed by the Asson River, the park features a variety of vegetation that grows along the stream's banks. When it was created, the preservation of flora and fauna was a major objective. An eco-grazing area was created there.

In summary, the Church of Saint-Jean-Baptiste in Montaigu is an example of Gothic architecture with an imposing façade and decorative elements. It houses side chapels, a choir, a main altar, and colorful stained-glass windows. In addition to its aesthetic appeal, it is also an active place of worship and a significant historical landmark for the local community. The Church of Saint John the Baptist in Montaigu has a rich history dating back several centuries. Here is a brief overview of its history: The original church in Montaigu was built in the 11th century, but little information is available about this early structure. Over the following centuries, the church underwent alterations and expansions, reflecting changing architectural styles. In the 14th century, the church was rebuilt in the Gothic style, with a spacious main nave, elegant vaults, and carved details. Construction was completed in the 15th century, giving the church its current appearance. During the French Revolution in the 18th century, the Church of Saint John the Baptist was used for secular purposes. It was converted into a community hall and suffered significant damage, including the destruction of decorative and religious elements. After the Revolution, the church was gradually restored and returned to worship. Repair and renovation work was undertaken to restore damaged architectural features. Over the years, modifications and improvements were made to the Church of Saint-Jean-Baptiste. Side chapels were added, stained-glass windows were installed, and religious ornaments were restored. Today, the Church of Saint-Jean-Baptiste is an active place of worship for the Catholic community of Montaigu. It is also a tourist and cultural attraction, attracting visitors with its Gothic architecture, stained-glass windows, and history. Religious events, ceremonies, and concerts are regularly held there.

. 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.
