These are the posts I found between the Heidebos parking and Axelsvaardeken. The first one is located in the intersection between the parking and Puttestraat, photo taken facing north. The second one is located in the intersection between Axelsvaardeken and Puttestraat, photo taken facing west. The third photo is a post that is located in the path between the first two posts, photo taken facing west.
