This is Batara, a concrete open-air pavilion built by the architect Anne Holtrop.
You can see more unusual objects in Arboretum Belmonte between 14 June and 15 September. A plastic bench that looks like a mangrove root, for example, a live herbarium or a chicken run in which a cosmopolitan chicken is created. These objects are part of the Beelden op de Berg (sculptures on the hill) art festival. Artists give their take - often inspired by Wageningen scientists on the friction between authenticity and fake. And what better time to ponder this question than when wandering through the greenery of the arboretum?
