Porta-Kanzel, Rock formation and viewpoint in Porta Westfalica, Germany.

Porta-Kanzel is a sandstone cliff on the Jakobsberg (235.2 m) in the Wesergebirge, dropping steeply to the southwest and west. It lies north of Hausberge, east above the Weser gap of Porta Westfalica, in the Minden-Lübbecke district. In 1877 a viewing platform was built, looking over the southern part of the gap and the Kaiser-Wilhelm-Denkmal across the river.

In the Middle Ages the Antoniuskapelle stood on this part of the Jakobsberg. In 1877 a viewing platform was built to open the cliff for tourism, giving a view over the southern part of the Weser gap and the Kaiser-Wilhelm-Denkmal on the Wiehengebirge side. During the Second World War, former ore-mining tunnels beneath the cliff were expanded into an underground production site (U-Verlagerung) to protect armaments work from Allied air raids; after the war some entrances were blown up, altering the western part of the rock.

The name Porta-Kanzel refers to the cliff's role as a pulpit-like lookout over the Weser gap, the Porta Westfalica. Since 1877 visitors have used the viewing platform built for tourism, which frames the southern part of the breakthrough valley and the Kaiser-Wilhelm-Denkmal on the Wiehengebirge side.

The viewing platform built in 1877 sits on the sandstone cliff of Jakobsberg, 235.2 m above sea level, north of the Hausberge district and east above the Weser gap. The cliff drops steeply to the southwest and west, so the platform edge is exposed; keep back from the rim. Access is on foot only, and the western part of the rock was altered when tunnel entrances were blown up after the war.

Below the Porta-Kanzel, former ore-mining tunnels of the Wesergebirge were expanded during World War II into an underground production site, a U-Verlagerung meant to shield armaments work from Allied air raids. After the war some entrances were blown up, which altered the western part of the cliff.
