The playground of the Vredehof school borders the rehabilitation garden of nursing home Pniël. Together with Pniël, funding was raised to transform the garden into an edible nature garden of 500 m2. The limited space means there is no room for a canopy layer, so it is defined as an edible nature garden created and designed along food forest principles. As well as being a therapeutic garden for residents of the nursing home, it is also a school garden for children: a beautiful cross-pollination.

De Geheime Tuin is a closed location and can only be visited through tours organised by Coöperatie Ondergrond. For tour information check: https://ondergrond.eu
