One of the tree houses (map)
Oldenburg is situated between Emden and Bremen. I had already decided earlier that this would be a day trip with two cities so I made a stop at Oldenburg and explored this town a bit. Also nice and small and there are enough interesting things to photograph. There were gardens of various kinds in the middle of the central city, constructed for an art project. You could see a Feng-Shui garden, some tree houses (miniatures only, though) and a few other things.
