La Chaire a Calvin is a rock shelter near the village of Mouthiers-sur-Boëme in the Département of Charente, situated in the valley of the Gersac stream.

The rock face of this rock-shelter has a sculpted frieze dated to the Magdalenian period; approximately 15000 years BP.

This site contains the remains of rhinoceros, red deer, beaver, wolf, Saiga Antelope, tarpan, reindeer and aurochs, as well as fox, hare and indeterminate birds.

Perforated beads were discovered which indicate some long-distance exchange with contemporary groups.

[6] John Calvin, a Presbyterian reformer, preached on a rock platform near this shelter when he was living in Angouleme in 1520.
