I’ve written before about the Trajectum Lumen light art installations to be found throughout the city. From simple to grandiose, they put the spotlight on Utrecht’s rich history. One of my favorites is the Ganzenmarkt tunnel. The lights are constantly changing colors, creating a psychedelic fairytale landscape that makes me think of Alice falling down the rabbit hole. Plus, the tunnel leads down to the Oudegracht, where you get a great view of the Stadhuis, plus some more lights under the Stadhuise bridge. During a past visit, this was one of the color sequences, though the shifts from one color to the next are more gradual.
If you’re visiting Utrecht or thinking about visiting Utrecht and are looking for things to do, a walk through the city, enjoying the lights, should definitely be on your list. The lights begin at dusk and go until midnight, 365 days of the year, so you can check them out whenever you like. It’s a nice way to cap off an evening.
