The Sun

In addition to the Dom Tower and Dom Church, you will also see the Academy Building on the Dom Square and the sun in front of the Academy Building.

This bronze statue of the sun was made in 1994 and its production has been quite difficult. There is a video of this on Youtube (Planetenpad Utrecht). Around the sun, Utrecht’s motto is “Sol Iustitiae Illustra Nos” (Sun of Justice illuminates us). The sun and the motto had been in use at the university for some time, but have taken on extra significance because around 1930 the University’s Astronomy Institute became world famous for its solar research by Prof Minnaert. You can find more about this in the Sonnenborgh


You can go through a gate to the Pandhof of the Domkerk on the left of the Academy Building. Take a look around here and definitely look above the entrance when you go out. To the left behind the academy building is a room in which the Union of Utrecht was signed, which brought an end to the 80-year war.
Under the Dom Square are still old Roman remains that you can visit at DomUnder. Also check the paving of the Domplein, where you can see the contours of the Domkerk and other churches.


Now walk to the Korte Nieuwstraat to the south. You pass a metal strip, from which water sometimes spouts, which marks the boundary of the former Roman castelum. Use the left sidewalk to find Mercury.

Remember that every meter you travel (adult step) is 1 million km in space. The sun and planet models are on scale!
