The Col de Pierre Pertuis is a pass crossing in the Swiss canton of Bern . It is located between the towns of Sonceboz and Tavannes and overcomes the watershed between the valleys of the Birs in the north and the Schüss in the south. The pass is at 827 m. The name is derived from the Pierre Pertuis rock formation , a natural and artificially extended rock tunnel ( Latin : Petra pertusa ) through which the road connection between Aventicum and Augusta Raurica led in Roman times . The rock passage is about 300 meters north of the pass. An inscription from the 3rd century above the northern tunnel entrance names Marcus Dunius Paternus as the builder of the road ( CIL 13, 5166 ):
- NVMINI (BVS) AVGVST [O] RVM
- VIA [D] VCTA PER M (ARCVM)
- DVNIVM PATERNVM
- IIVIR [V] M COL (ONIAE) HELVET (IORVM).
The pass road ran through the tunnel until the beginning of the 20th century. This section of the Roman road is included in the federal list of protected cultural assets and is therefore under national monument protection.
During the mobilization from 1914 to 1918, engineering troops of the Swiss Army built a new road, better suited for motor vehicles, that bypasses the old tunnel. In 1932 a new mountain road built by the unemployed was inaugurated. Since November 1997, a 2100 m long, directionally separate motorway tunnel on the A16 has been running through the mountain.
