The Austrian artist Lois Weinberger demarcates a strip of land on the grounds of the Pede windmill. He does this with horizontally placed doors, allowing nature to take its course within the frame. This piece of land becomes part of the 'natural' landscape through the spontaneous growth of the vegetation there.
In the complex imagery of the 16th century, almost every object also conveyed meaning. Doors symbolised access to heaven and hell and depicted the transition from one state to another. Bruegel uses doors for carrying food or as a bird trap.
