We have now
arrived a the wide Northern entrance, where a luxurious green area has formed.
Here is the point where the river, joined by the Gutturu Farris river, gets
inside the cave. At its top there is the entrance of a small passage, where was
found a fossilised bone, fossil we still don t know the origins. The pavement
inclination here allowed the formation of rimstones, most of them no longer
active.
Human activity in this side of the cave is proven since ancient
times. We can notice how the stratified layer under the flowstone still keeps
burned soil, evidence of huge fires once burning above its grounds. The fire
served to both warm up the area and allow the people to live, and as a source
of light, to light the torches needed to cross the dark tunnel for the whole
length. Bibliographic sources also mention the existence of a chapel, which was
likely to be the Saint John’s chapel, which gave the name to the cave. An
archaeological excavation in this area could definitely give us interesting
information, since none has been done to date.
