Erosion Furrows of Atri
The hill town of Atri is famous not only for its Roman and Renaissance monuments but also for spectacular erosion furrows, formed by slow erosion of the clay soil under the influence of wind and water. They were known in the past as ‘Bolge’, a word which Dante used in “The Inferno” (“The Divine Comedy”) for ‘ditches’, or else as ‘Scrimoni’, or ‘ridges’.
In 1995 there was founded a 350-hectare Regional Natural Reserve Calanchi di Atri. Erosion furrows are very picturesque in the daytime but in the night they resemble a fantastic moonscape. It is possible to take a romantic midnight walk organized by a Regional Natural Reserve.
