The Woodland House is located on the border of two of the main geological areas of France:
- to the East, the Paris Basin with its horizontal stacking of limestone , chalk, sand and clay layers, dating from the Secondary and Tertiary eras,
- to the west, the Armorican Massif with its almost vertical bars of sandstone and shale, dating from the Primary era, resting on an even older base (Precambrian).
It is the ideal place to learn about the geology of the two main rock types: sedimentary in the east and metamorphic in the west.
