OK my family thought I went mad when I started taking pictures of these little fences I saw on the pavements in Zierikzee. What amazed me was the variety of sorts and I wondered why they were there. Couldn't find a reason but can imagine it beeing to prevent trespassing. But isn't a pavement for everyone to walk on? Funny.
The next photo shows a whole row of pavement fences. As you can see it does prohibit you to walk over the pavement. To enter this door you have to pass through these two fences.
A fence attached to a boundary marker. Another kind of fence. As you can see there are fences in various designs.
