Kallnach is considered the longest Straßendorf (a village that lies almost entirely along a single road) in Switzerland. It stretches along the foot of a moraine of the Rhône Glacier at the edge of the Grosses Moos. It lies on the road from Lyss through Aarberg to Kerzers. It has a train station on the Broyetal Line (which connects Aarberg and Kerzers). The remains of a Roman road which connected the settlements of Aventicum and Petinesca have been found in the Aspi. Excavations in 1989 revealed remains which have been variously interpreted as a restaurant, a customs office, or a horse-changing station. In the seventh century, Romans still lived in the area of today's Kallnach, as evidenced by their remains and graves.
