When entering this area you first see some works by Mr. Jeus (now known as Huascaya). He used to live there, as this was his playground for some years.
Bit of a special location, as this is now private territory. It used to be a public space (parking space for 'Druk in de Weer'). So do be friendly when entering the space... if the gates are open. 
Don't forget to continue, there is more to see here.
