Castrovalva is a lithograph print by the Dutch artist M. C. Escher, first printed in February 1930. Like many of Escher's early works, it depicts a place that he visited on a tour of Italy.
It depicts the Abruzzo village of Castrovalva, which lies at the top of a sheer slope. The perspective is toward the northwest, from the narrow trail on the left which, at the point from which this view is seen, makes a hairpin turn to the right, descending to the valley. In the foreground at the side of the trail, there are several flowering plants, grasses, ferns, a beetle and a snail. In the expansive valley below there are cultivated fields and two more towns, the nearest of which is Anversa degli Abruzzi, with Casale in the distance.(Wikipedia)
