Castelfeder (from castello, the Italian word for castle) is nestled between the holiday villages on this strategically important porphyry hill. Castelfeder is a prehistoric and Roman as well as early medieval settlement characterized by the remnants of several structures and buildings on a large hilltop. It is a true place of energy and a popular destination for excursions, especially in spring. Today, sections of the encircling defensive wall with the well-known "Kuchelen" castle walls, and parts of the Barbara chapel from the 6th century can still be seen. In addition, the sunny Castelfeder hill fascinates with its unique and diverse flora. A special feature is the smoothly polished fertility chute carved in porphyry. It was a central component of an ancient cult. Rumor has it that even today sliding down it results in the arrival of a much yearned-for baby.
