DOMunder reads the ground with a smart torch
Beneath the Domplein, a guided discovery tour follows Roman and medieval remains; exploring on your own is not possible.
Traiectum beneath your feet
Remains of the Roman fort are viewed in situ. Note the stone, position and layer and ask which parts are visible in the original and which are supplemented digitally.
Middle Ages and storm damage
Later building phases and the storm of 1674 lay new layers over the Roman story. Use the torch to follow one transition between periods precisely.
A tour instead of opening hours
The desk at Domplein 9 is open daily, but that is not the same as access to DOMunder. Only a ticket with a start time and guide opens the underground route.
Before you go
Book a start time online; stairs and the lack of a wheelchair entrance limit accessibility, and the film contains flashing lights and sound.
