This is lock number 11. On the other bank you can admire the Groulaie forest.

Beautiful medieval castle. The main building is more recent. As a side note, the Isac River fed the castle's imposing moats, now dry, before being channeled to the current marina.

The Monkey Bike Bar is a must-see place (Bar) on the Nantes-Brest canal! ideally located on the port of Blain with a terrace to quench your thirst with a nice view! Plus there is a bike shop behind the bar (Cycles riflet). Don’t hesitate to stop by! schedules available on Google and social networks, depending on the seasons.

Located at the exit of the town of Blain, just next to the Nantes-Brest canal, this old medieval fortress invites you to walk in the footsteps of its prestigious guests such as the King of France Henry II, Queen Catherine de Medici or Duchess Anne of Brittany.

The Château de la Groulais, or Blain, is a medieval fortress located in the town of Blain, in Loire-Atlantique. Built in the 12th century by the Duke of Brittany Alain Fergent, then enlarged in the 13th century by the constable Olivier I de Clisson, and heavily remodeled in the 16th century in the Renaissance style, it was part of the defenses of the Franco-Breton border with the castles of Vitré, Fougères, Châteaubriant, Ancenis and Clisson.
