The Waterloopbos - official address in Marknesse, but as a matter of fact located nearby the small village of Kraggenburg - was built in the early 1950s. It offers 35 scale models of major water works from all over the world. Of course the famous Dutch Delta Works were tested here, but also for instance the ports of Rotterdam, Lagos, IJmuiden, Istanbul and Bangkok. Testing and simulating reality by engineers of the Waterloopkundig Laboratorium was done in the 50’s and 60’s of the 20th century. The Waterloopbos is located in the Noordoostpolder, one of the many Dutch polders. As this ‘new’ land lies five metres below sea level, so water could flow naturally to the test setups without needing pumps. With the help of this flowing water plus the creation of weirs, dams and wave machines, the engineers were able to test the influences certain forces would have on their proposed constructions. No more testing has been done here for decades and in many places the models have been reclaimed by nature. The old water ducts, weirs and sluices are now full of plants and shrubs. Parts of the Waterloopbos look like a green jungle, where the forest interacts with the dated technology. One of the models - a gigantic structure of two concrete walls - has been transformed into a massive artwork: Deltawerk // .

The Waterloopbos offers 35 scale models of hydraulic projects from all over the world. Off course the famous Dutch Deltawerken were tested here. The Deltagoot (Delta flume), a gigantic structure of two concrete walls in the Waterloopbos , served as the test location. Nowadays it has been transformed into an imposing memorial to the research once conducted in these woods. In the meantime this test location has lost its original function. In 2016 it was declared a Rijksmonument (Dutch national monument). The artists RAAAF | Atelier de Lyon were then asked by Natuurmonumenten (Society for Preservation of Nature Monuments in the Netherlands) to create a massive artwork from the famous 'Delta flume'. “Deltawerk //” became its title. And massive it has become: RAAAF and Atelier de Lyon have dug out the colossal wave basin; its concrete walls now tower some seven meters over the visitors. Enormous concrete panels were sawed out of the 250m-long Deltagoot, which were turned and placed at different angles to visualise the devastating power of the water. As years go by, nature will reclaim the work of art and mosses and ferns will take over (as in the rest of the Waterloopbos ).

The Noordoostpolder is a landmass of reclaimed land in the former Zuiderzee on average more than four meters below sea level. It turned out that the bottom of this sea is very suited for the cultivation of tulips. Nowadays it has one of the largest area of bulb fields in the Netherlands with many multi-acre fields of tulips that bloom every spring. During the so called ‘Tulip Festival’- from about mid April until around the beginning of May (depending on weather conditions - visitors can enjoy the vast tulip fields along a special bike and car route. The tulip route through Noordoostpolder has a length of about 100 km’s, leading visitors past the most beautiful tulip fields.
