This small dig is at the corner of Apostolou Pavlou (Apostle Paul Street) and Dim. Eginitou west of the Areopagus. Discovered at the intersection of two ancient roads, the cave walls are carved with images including Pan, a nymph, and a dog. There seem to be no ancient references — and almost no contemporary ones online. Enter the north gate to the Pnyx, immediately turn left.
