The Domplein — the square in the heart of the city where you will find the Domtoren and the cathedral — has a long history. The square was originally the site of the Castellum Trajectum, the Roman fortress established nearly 2000 years ago to protect the northern border of the Roman Empire. The sign in the picture above marks where one of the entrance gates to the fortress was to be found.
In fact, they have found the foundations for the old fortress and you can see some visual depictions of what the fortress would have looked like through various apps now available. I think you also get to learn and see a bit more on the DomUnder tour (which I haven’t had a chance to take yet).
Still, you can get a sense of the size of the fortress due to some installations you’ll see in areas around the Domplein. The size starts to sink in when you realize it encompased the whole square and then some. The markers in the ground are bronze-ish metal pieces flush to the ground, with lines drawn in depicting various Roman Empire borders. They’re easy to miss, and even easier to puzzle over if you don’t know the meaning. It took me a few years to finally figure it out.
However, in the evening, they at least become a bit harder to miss. As part of the Trajectum Lumen displays, they light up and emit a watery mist every 15 minutes or so. The marker on Domstraat is pretty impressive, the way it lights up along one of the buildings and has the cathedral behind it.
There’s another by the Academiegebouw, which I managed to capture once, years ago.
More recently, I finally caught the one on Servetstraat, in front of the Domtoren. It’s a cosy little street with a nice mix of shops and restaurants, all in the towering shadow of the Domtoren. Standing along any of the old fortress borders, it’s impossible not to look around and think of all the history this one small section of Utrecht has seen and experienced. And now we all become a little part of that long history.
