[1] The theme park, which opened in 1991, was made to look exactly like the original illustrations in the book.

Thorbjørn Egner saw the theme park while it was under construction, but did not live long enough to see it completed.

During the summer actors in the park portray the residents of the fictional town.

In addition the visitors of the theme park can see the different main characters in the book: Commissioner Bastian and Aunt Sophie, as well as the three robbers, Kasper, Jesper and Jonathan.

The theme park also has a functioning post office, which uses the postal code "4609 Cardamom Town".
