the west brabantse water defence line was built in 1627 by the states of zeeland and zuid-holland. over the course of its tumultuous history it has served the dutch as a defensive stronghold to protect the region’s valuable trade position. it has seen and staid many assaults over the years, but in a recent spell of peace it has been converted into a more communal public landscape — largely with the aid of a new observation tower by RO&AD architecten. the tower serves the public almost as an arena, with the inward facing side completely open, and the side facing the river with tiny slits with chance movements to view the landscape. it looks almost like a siege tower or a 18th century fortress.

according to RO&AD, the tower was constructed without the use of drawings, with the design team instead relying on a 3D model. with the use of this model, and a bevy of already prefabricated parts, the contractor assembled the wooden structure in an IKEA-like fashion. it now towers 26 meters over the park and can accommodate up to 225 people.

today, the structure serves the community as an open theater, an info center and a watchtower. tourists and locals alike come here to take in the landscape and explore the festive creation which towers above the trees. this project prompts us to rethink how we interact with the natural environment and how we engage with one another.
