Duno, Circular rampart in Heveadorp, Netherlands
The fortified structure stands on elevated terrain near the Rhine River, featuring earthen walls and a moat surrounding an oval-shaped defensive position.
Built around the year 1000, the early medieval fortification contained wooden palisades to monitor river traffic and protect a crossing point for horse-drawn carts.
The archaeological national monument integrates with the Duno estate, which developed from a landscape park containing a gazebo, tea house, and rose gardens in 1800.
The site remains accessible through public pathways maintained by Geldersch Landschap Foundation, which manages the 65-hectare property since 1932.
Archaeological excavations revealed evidence of iron production and pottery manufacturing from medieval times, indicating industrial activities in this strategic location.
