The reconstruction is great! But we left some parts in ruins, which preserves the character of an old building.

A great detour to Saint Aignan, the Les Pêcheries de Guerlédan restaurant is very welcoming, with bike parking, a generous meal and welcome. Crossing the village, you can reach the canal a little further on via the lock.
