A quirky little idea by DUS Architects: put a 3 x 3 metre box next to the Amsterdam public library, line its inside with mirrors, and put a tree in the middle.

The Urban Woods pavilion is part of the Liefde in de stad (Love in the city) art project about which we wrote earlier. You can visit the forest (a short walk from Central Station) until June 27.

A clone of the famous Anne Frank chestnut was planted in a park South of Amsterdam last friday. Alderman Marijke Vos and the CEO of the Anne Frank Foundation, Hans Westra, planted the young tree in the Amsterdamse Bos in Amstelveen, Metro reports.

Anne Frank used to look out on the tree when she was hiding for the Nazis, and wrote about it in her famous diary. Lately, the tree has been developing a disease, which led to the foundation deciding to plant 150 cuttings before it was too late. The other 149 chestnuts will be planted over the upcoming years.

Artist collective Uitschot came up with this wooden game console called Gameboom (Game tree) in 2005.

Cut and installed for the first Day of the Park in Leiden. Location: Cronesteynpark across the water playground. For: city children who are allergic to nature, get dragged along by their parents but would rather game. Detail: functioning slot.

The Olympiaplein in Amsterdam is located in my neighbourhood, the Olympic Quarter. I must have walked and biked past this spot dozens if not hundreds of times. And yet when I did so last week, the oddness of this fence struck me for the first time. Its builder and designer has taken special care to curve the fence around some of the trees, but has locked other trees out. It is clear that this was done on purpose, but not why.

Perhaps this is a reflection on the power of man over nature. Trees cannot walk, but even if they could, people would get to decide where. Or, more likely, it is a statement of the power of man over man. We, the city council, decide where our fences run. If we want them to zigzag, we’ll make them zigzag. If we want them to form obscene drawings to observers in outer space, obscene drawings it is. Or perhaps the architect merely mused on the nature of borders in general, with the rows of trees forming one border, and the rows of steel mixing in in an oddly compromising way.

In the end, the solution is far more prosaic. This fence, designed by Ruud-Jan Kokke, replaced its modest predecessor in 2007. The district council had decided to cut down 78 trees to make room for the fence, and this decision led to a storm of protest. Once the district of Oud Zuid had decided to give in to the complaints, the fence builders had already started (Dutch). The decision was then reached to have the fence curve out whenever it met with a tree. And so all my philosophies proved right, in the end, though not in a way I expected.

The city commissioned Gabriele Merolli to make a series of photos of The Fence, and he put them on the web.
