Kaj Törngren, a man who loved nature, left the majority of his estate, a farm in Sipoo together with its forests and fields, to the Finnish Natural Heritage Foundation. He mostly allowed his forests to grow in peace and kept some of them fully intact. This valuable legacy enables us to protect three forests, which will be called Törngrens skog, Fågelskog, and Lillskogen.

These three forests standing close to each other on an exuberant ground cover a total of approximately 13 hectares. The largest of them, Törngrens skog, includes a number of great aspens and decayed wood in large amounts. A fascinating path goes through this magnificent grove-like forest of lushness and leads to the proximity of the Keravajoki river and the connection of the Haarajoki river’s arms. The size of the trees together with the alteration of deciduous and coniferous trees create a true atmosphere of a primeval forest.
