"Starting in 1978, I photographed signs with the words Verboden Toegang (no entry) on all my walks. It has now become a collection of nearly a thousand photographic documents. Initially in black and white. Later on, in colour. Through the use of language, it is made clear that someone is not welcome in a certain area. Language has the advantage of clarity.

Yet how can one photographically record a delimited area without using language? What are the tools that replace the signs with inscriptions?

This book is a visual story in which red-and-white or black-and-yellow cordoning tape, traffic cones and/or blocks and crowd control barriers act as protagonists. These are the elements that, in the absence of language, must make clear whether a site is physically accessible or not."
