Granite shapes both the landscape and the local history of Saint-Pierre-De-Plesguen. There is also a walk by the ponds, paths through the woods, and specific dates for the market and farm shop. When planning your stay, consider whether you would like to allow more time for granite heritage, outdoor activities or local produce.
Church and Granite Heritage
The Église Saint-Pierre is listed as a historic monument. The history of granite also offers several points of interest: granite quarried in Saint-Pierre-De-Plesguen was used to build the Dinan Viaduct. Rocher Abraham was an important granite-working village with quarries and workshops where the stone was cut and shaped.
These details can be read as a story that follows the stone from quarrying to processing. Anyone interested in architectural history can look beyond the church to the work done with the material: quarries and workshops shaped Rocher Abraham, and local granite was used for the Dinan Viaduct. The Massif de Saint-Pierre-de-Plesguen completes this picture as a granite plateau whose landscape is characterized by woods and bocage hedgerows.
Ponds, Woods and Paths
The Espace naturel de La Vallée is in the heart of the village. It is a good place for a walk around the ponds. This is one way to include nature in your visit without planning a longer route; no duration is specified for the walk.
The woods of the Massif de Saint-Pierre-de-Plesguen offer another option, with numerous hiking and walking trails running through them. You can choose between a walk by the ponds in the nature area and trails through the woodland. The granite plateau, woods and bocage hedgerows give the landscape its distinctive character; when planning your visit, you can therefore treat nature and granite heritage as different but complementary areas of interest.
