The first of the two grottoes is named after the ancient god Apollo, whose statue dominates the entire space. The walls around this sun god’s statue used to be lined with hundreds of amethysts, only some of which have been preserved to this day. The amethysts, illuminated by the flickering flames of torches, created the impression that Apollo was actually shining in the middle of the dark space. The glow of the precious stones was further enhanced by water features and fountains, whose murmurs and reflections complemented the overall theatrical impression.

Apollo's Grotto
Bishop Karl von Liechtenstein-Castelcorn
The allegorical meaning of the grotto’s decoration is directly related to Bishop Karl von Liechtenstein-Castelcorn, whose family name, Liechtenstein, can be translated as “light” or “shining stone.”
The Bishop as Apollo
Apollo personifies Bishop Karl himself, who pierces the darkness with rays of light, in this case representing faith and knowledge. The darkness is represented by oak trees with fauns, wild animals, and the dragon Python, whom Apollo defeated. This allegory was intended to commemorate the bishop’s role during the recatholicization, which revolved around spreading the light of the Catholic faith and defending it against heresy. There are also heraldic symbols of Bishop Karl, namely a lion carrying a triangle and an eagle with a star.
A Spectacle of Splendor
However, the grotto was not just a religious metaphor. It was also a spectacle designed to entertain and impress guests. In the past, visitors could see the statues of animals spouting water as well as an unusual effect in the form of a spring of water gushing from a mound covered with pebbles, on top of which a candle was lit.
