The Castle is a 1926 novel by Franz Kafka. In it a protagonist known only as K. arrives in a village and struggles to gain access to the mysterious authorities who govern it from a castle.
As for many other Kafka novels book cover creators love using some abstract painting and forms based on absurdity of Kafka's plots. Or just use some sad castle photos/pictures.
Some examples of existing solutions
What we wanted to do is to avoid any abstract castle illustrations and absurd stuff.
Basicly the idea was to reflect the pressure main hero feels from the castle.
The name (CASTLE) is illustrated as a castle. In the bottom — main hero. Castle is pushing. That's it.
