Sonnenborgh is a bastion and observatory in Utrecht. It is one of the four bastions Emperor Charles V had built that was used in Utrecht in 1552. In the casemates behind the three-meter thick walls are still cannon holes. There is also a 16th century latrine and a well. In addition, the museum has a collection of telescopes that were used to study the stars and planets.
