The best traffic-free bike rides around Janzé

About the small 19th-century church.

To see the medieval castle (its ruins anyway)

Long greenway between Châteaubriant and Bain de Bretagne. Very smooth rolling.

I did not visit the museum but I enjoyed the path, which connects the Châteaubriant → Bain-de-Bretagne greenway a little further south.

Magnificent greenway, rolling and shaded. Less flat than I expected.

Church attested in the 12th century. Nave flanked by a north aisle, built between 1540 and 1549 (date of consecration by the bishop of Rennes), and by a south aisle, built between 1603 and 1605 (dates inscribed). Inscription on the south door: ESTANT NOBLE ET DISCRET PRESTRE : RENE DE L'ESPINAY RECTEUR DE PIRE : SIEUR DE LA GUAYE FUT CESTE EDIF : CE COMMENCE. SA (NC) TE DEUS SA (NC) TE FORTIS SA (NC) TE IMORTALIS MISERERE NOBIS SA (NC) TE PETRE ORA P (RO) NOBIS : TOUT EST A Dieu 1603. The choir was first rebuilt in 1627, then surmounted by a dome struck by lightning in 1741, then again between 1752 and 1775, flanked by side sacristies. Bell tower at the top of the nave rebuilt in 1669. In 1874, architect Aristide Tourneux had a bay added to the north of the nave and a porch-tower surmounted by a spire built. Stained glass windows signed and dated: Claudius Lavergne 1882, and also stained glass windows from the Rault workshops and the Carmel of Le Mans. South wall of the enclosure redone in the 19th century with a monumental corner staircase.

This parish belonged to the Collegiate Church Notre Dame de VITRE until the year 1116. It was then handed over to the Abbey of Saint Melaine (in RENNES). SAINT-DIDIER, the patron saint of the Parish, is undoubtedly the holy bishop of RENNES who lived at the end of the 7th century. His statue is part of the altarpiece of the high altar (1721), as well as that of Saint GOLVEN.

The church of Saint-Sulpice (17th century). Dedicated to Saint Sulpice, bishop of Bourges, the church of Ossé consists of a single nave ending in a straight chancel, to which two chapels have been added, forming the transepts. It has no style and may partly date back to the 16th century, as indicated by the ogival window of its chancel, now walled up. The North chapel, dedicated to the Virgin Mary, and originally reserved for the lord of Charot, was built in 1611. The other chapel, dedicated to Saint Nicholas, also seems to be from the 17th century. Le Plessix d'Ossé was the manor house of the parish. In 1440, Duke Jean V settled a dispute concerning the right of burial in the church of Ossé between the sieur du Pan, lord of Plessix, and the sieur de Montbeille, lord of Grées. The ecclesiastical superiority belonged to Ossé to the baron de Châteaugiron, but the lord of Plessix enjoyed the rights of founder and patron; this was declared in 1694 by Gabrielle Glé, marquise de la Vallière and lady of Plessix (National Archives, P. 1721). Jacques Le Prestre, baron de Châteaugiron, having acquired Plessix in 1744, took possession of all these honorary rights and had his coat of arms placed in the choir and on the high altar of the church of Ossé. As for the lord of Charot, he had his tomb, his pew, and his coat of arms in his reserved chapel. The bell tower dates from 1899. The altarpiece of the Holy Trinity dates from the 17th century.
