Heinrichsburg - now known as the Dwarf Castle.. Very interesting is the representation of the castle. Building material is tuff containing fossilized reeds that remotely reminds stalactites and hence adds to the castle mystery. Romantic imitation castle from the early 20th century is located in the premises of the zoo in Usti nad Labem. Today from the castle remained only a small part, but to everyone who enters here, admire his special cool atmosphere...
