Tips from the Community
Located west of the town of Petit-Mars, the Port de la Rivière is one of the few public spaces in the town providing access to the Erdre River. About fifteen boats and rowboats moor there year-round. A protected natural area, its banks are accessible on foot. A footbridge allows you to cross one of the branches of the "most beautiful river in France" to continue your stroll closer to the water. Picnic tables are set up there to make the most of this bucolic spot, which welcomes visitors every year at the end of August. https://www.petitmars.fr/decouvrir-petit-mars/tourisme/visite-guidee

Built around 1840, it was destroyed by fire in 1900. It is also known as "The Burnt Mill." From here, you can see the Erdre Valley and the Mazerolles marshes.

"In memory of the four resistance fighters killed while escaping from the moving train from Rennes, which was taking them to deportation on the night of August 3-4, 1944. Jean-Marie L'AZOU was wounded at this location and executed on the morning of August 4, 1944, at La Sigoulière. Marcel LE DROGOFF and Pierre GAUTHIER were killed after jumping from the same train; Robert THOUÉMENT was found dead in a field before Pas de Mail. Monument built by the inhabitants of the village of Basloirs in 1947 and renovated in 1969." In Saint-Mars-du-Désert, 31 prisoners managed to escape from two different train cars. Four lost their lives. Following the Allied landings, the Germans organized the evacuation of the Sainte-Marguerite camps and the Jacques-Cartier prison in Rennes. The last convoy, 54 cattle cars, left Rennes on the morning of August 3. Nearly 2,000 resistance fighters, men and women of French, English, and American nationality, along with German deserters, were taken to Germany. In the afternoon, the train stopped in Nantes, where railway workers managed to smuggle tools to the prisoners. The following night, as they approached Saint-Mars-du-Désert, 31 prisoners managed to jump from the train... But a German patrol was stopped at the next level crossing... https://fr.geneawiki.com/wiki/44179_-_Saint-Mars-du-D%C3%A9sert_-_La_Nuit_du_3_au_4_ao%C3%BBt_1944
