The excavations revealed a 5 m deep irregular-sided rock cavity at the top of the cliff, which was used at the same time as the medieval chapel, tapering to a square at the bottom. The hermits of the time preferred to live in caves and cells carved into the rock – but not in a cavity like this, open from above. So the original purpose of the excavated rock cave remains a mystery. The hermits may have lived in surface structures of which only very faint traces have been found. In many ways, Borostyán-kő could have been an ideal site for a hermitage. It was in the Bakony mountains, but close to the monastery, which provided a secure background. In addition, the rock, the abundant spring at its base and its surroundings provided favourable conditions that attracted communities to the site already in prehistoric and Roman times.
