The available information on the burial crypt of the Schwarzenbergs turned out to be rather fragmentary. According to my knowledge, it should be located close to the altar of St Nicholas of Tolentino in the Augustine Church and was in use from 1682 to 1789. By spring 1757, the crypt was the final resting place of three reigning princes, two princesses consort, another married princess née Schwarzenberg, and four children.
However, the problem is that I have never seen the crypt with my own eyes. It is hard to imagine it being accessible to outsiders at all; admittedly, however, I have not tried to apply to the church authorities or the family for a visit. Besides, I do not know whether the main landmark, the altar, still exists or what its exact location in the church is. Furthermore, even the terminology is rather unclear: both ‘crypt’ and ‘chapel’ are found in the sources.
Thus, my description of it is purely imaginative. Despite being based on research of an academic quality, my ambitions with the narrative are mostly artistic. It therefore seemed disproportionate to bother persons in charge for the sake of pursuing such a high level of historical accuracy.
