The Great Menhir of Pierres Meslières

Highlight • Other

Large quartzite menhir, 3m76 high. It was probably part of an alignment of several dozen menhirs, which have now disappeared.

Lacets du Mont Piron

Highlight • Other

The toughest climb in Loire-Atlantique, in my opinion. Quite long (> 500 m) with an average gradient of 12% and sections of over 18% according to my Garmin. The winding route reinforces the "mountain" feel.

Église Saint-Martin

Highlight • Other

Church built in 1851 to replace an older church deemed too small, which stood on the site of the current war memorial.
Good bakery to the left of the church.
