The Origin of the City

Utrecht originated 2000 years ago with the construction of a Roman fortress, the remains of which lie four metres under the Domplein, in the heart of the city. The Domplein Foundation aims that the history of the city is still tangible on the square through visitor centres, tours and events. OKRA realised the marking of the Roman fortress wall and through this intervention a suggestion to the origin of the city is made visible around the Domplein.

Small Intervention, Major Significance

The design consists of a small intervention. The underground fortress wall is once again indicated on street level with a family of corten steel linear elements, right above the original fortress wall. The marking itself is engraved with an indicative map of the border of the Roman Empire. In the evening is illuminated from underneath with a green light and mist, which changes during different times of day, public holidays and events that occur in the city.


By making the former fortress wall visible again through OKRA’s installation, people in the city can once again see, enter and touch the former wall. It raises awareness among the inhabitants and tourists of the rich history of Utrecht. The construction of the marking has also proved to be a boost in the awareness of the entire area of the Domplein.
