It is noted as the birthplace of the Roman Catholic Saint Louis de Montfort, who is considered to be the pioneer of the field of Mariology.

It is now jointly owned by the three Montfortian congregations he formed: the Community of the Holy Spirit, the Daughters of Wisdom and the Brothers of Saint Gabriel.

[4] Human beings have made their imprint on the district of Montfort en Brocéliande since prehistory.

Ancient menhirs can be seen in the forest of Montfort, but it is at the end of the 11th century when the first castle is built.

The major revolutionary event is the one celebrating the execution of Louis XVI, accompanied by a hatred oath to the royalty and to the anarchy.

In the first version, the legend says that a young and beautiful girl, a prisoner of the Lord of Montfort, is moaning.

She, miraculously transformed into a female duck, flies through the window of her cell and settles on the castle's pond.

She understood very fast what was waiting for her and, catching sight of Saint-Nicolas Church, started praying the saint, promising to thank him if she could escape.

She prayed Saint Nicolas, begging him to allow the animals to be witnesses of her innocence and to make them accomplish every year her wish on her behalf if she had to lose her life.

The story became so famous that as it is written in many documents dating from the following centuries, Montfort-sur-Meu became Montfort-la-Cane for more than 300 years.

However, as only the archives dating from later than the 15th century have been kept, many stories are missing even though, as an ecclesiastic said, "In the past, these events became so common that we were not taking time to write them anymore".

The town is also home to pig slaughterhouses for pork production, owned by Cooperl Arc Atlantique.

From the medieval castle, there still is Papegaut Tower (14th century) which now houses the ecomuseum of the district of Montfort.

Parc Municipal Edouard Guicheteau, mayor of the town from 1853 to 1871, bought for private use the old meadows of the Thabor, possessions of the prior Saint Nicolas, to convert them into an English garden.

He diverted the Garun to assure the water circulation and planted yews and exotic conifers.

This path, made of two loops located in the heart of the district of Montfort, offers the viewing of diversified natural places (humid meadow, landscape parkland, shores, pond, sunken lanes, hedged farmlands, woods).

Located in Papegaut Tower, the ecomuseum invites you to discover the culture of the district where history and legends are very close.

Different permanent exhibitions are offered (the duck legend, the architecture of the district of Brocéliande, Montfort during the Middle Ages, the traditional suit, games about nature).

You can also find many pedestrian paths around Montfort-sur-Meu and a big swimming pool in the town centre.
