Unusual dimensions for a dolmen. I visited it on a weekday and had the site all to myself. Truly impressive. Also worth seeing is the chestnut tree at the entrance, which tried - but apparently failed - to swallow a megalith at the entrance to the dolmen. Toilets with a tap. Benches.

The Sainte-Marie-Madeleine church was built in the 19th century in a neo-Gothic style by Aristide Tourneux, an architect from Castelgiron. With a touch of humor, the town's priest in 1912 wanted to give "cats to the girons": Arthur Regnault, a sculptor, therefore sculpted cats at the four corners of the bell tower. Having collapsed in 1998 following a severe storm, the bell tower was rebuilt identically in 2000.

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.

With nearly 20 meters long, 6 meters wide, and 4 meters high, the Roche-aux-Fées remains the largest dolmen in France and one of the best-preserved in Europe. It is composed of a schist-covered passage formed by four chambers whose meaning has not yet been revealed. Although the construction of this monument dates back to the Neolithic period, around 2000 BC, specialists remain perplexed about its construction method. The site is impressive. And when you know that some stones weighing over 40 tons come from several kilometers around, you wonder how the inhabitants of the time managed to move them there. Such a site could only inspire stories, legends, and beliefs. One of them tells that the fairy Viviane, aided by fellow fairies, would have built this imposing monument... in one night. Another concerns lovers: to know if their union will last, couples must walk around the Roche-aux-fées, each in a different direction, and count the stones. If they find the same number of stones, their future will be bright! Through a mysterious alignment during the winter solstice on December 21st or 22nd, the sun rises facing the entrance of the dolmen. At that moment, the light rays magically illuminate the stone located at the back of the covered passage. Access is free and open. The small surrounding roads are charming and quiet.
