DOMunder is an archaeological experience beneath Domplein itself: you descend underground to walk among two thousand years of Utrecht's layered history — from the Roman fort (castra) that founded the city in 50 AD, to the Gothic cathedral, to the ruins of the nave the 1674 tornado destroyed — all preserved under the square where recent excavations found them. The tour is inventive: each visitor carries a smart flashlight that lights the artefacts and triggers their explanations as you move through the dark — you discover for yourself rather than being led. An interactive experience joining Roman and medieval history in one place beneath the city's feet. By booked guided tour only, right on Domplein — it completes the story of the tower and church from its deepest angle: how Utrecht began.
