On the south-eastern side of Jehla (superb views), towards the end of the wooded side chasm you will find a hidden altar, known as the Brethren's Altar. Frames and niches for the Stations of the Cross pictures and statues of saints have been hewn into the sandstone rocks around a small plateau accessible via stone stairs.

According to a folk tale, between 1515 and 1614 when the Kamenice Estate was owned by Protestant nobility, Catholics used to meet here in secret; the roles reversed after the Battle at White Mountain when secret masses were held here by the protestants. According to some ethnographers, these folk tales originated in the first half of the 19th century and this place of worship was established here in 1867. During the renovation work of 1887, the pilgrimage place took on a Baroque look, and a richly decorated altar with statues of the saints and angles was created below the rocky overhang.
