Our medieval sources unanimously testify that St Gerard, before he began his episcopal service, lived a ‘contemplative life’ in Bakonybél. The exact location of his hermitage may be indicated by a record from 1230, which mentions a chapel of the Virgin Mary “above the rock of St Gerard”. Less than 1 km from the medieval monastery, a small rocky outcrop called Borostyán-kő (‘Amber Stone’) rises spectacularly from the valley of the Gerence stream. Our research in 2016 has already indicated that a chapel stood on top of this rock in the Middle Ages, so all evidence pointed to the fact that in the 13th century the site was still called the Rock of St Gerard. Of course, we could not rule out the possibility that, nearly 200 years after his martyrdom, the memory of where Gerard’s hut once stood might have faded. However, in 2022-2023, carbon isotope analysis of human bone remains found here yielded important results: the chapel had been built long before, by the mid-12th century at the latest. Moreover, the artifacts recovered also point to a more permanent occupation of the site. Of particular importance is a metal stylus, which suggests the presence of a learned clergyman. It is undoubtedly impossible to verify by archaeological methods, but the results strongly confirm the earlier suspicion that St Gerard and his hermit companion Maurus did indeed spend their hermit years here.
