Kasteel van Oss

The Kasteel van Oss was a medieval fortress whose foundations remain beneath Burchtplein square today, made visible through glass and ground markers. The site shows where thick stone walls once stood, outlining the fortress's footprint on the paved surface.

The fortress was built around 1374 to defend against the Duchy of Gelre and became part of the city's defenses when Oss was granted city rights in 1399. This timing linked the castle to the town's growth and development as a settlement.

The square uses its medieval past as a visible element of everyday life, with foundations displayed beneath glass for visitors to see and understand. Walking across Burchtplein means treading over what was once the heart of the city's defenses.

The best way to experience the former fortress is by walking across Burchtplein, where you can see the foundations through glass plates and pavement markers. The site is open to the public at any time, allowing you to explore at your own pace.

An amateur archaeologist discovered medieval bricks in 1994, which triggered excavations that revealed the exact location of this long-lost fortress. This chance finding led to the systematic uncovering and preservation of the site for public viewing.
