Bringing far away closer by

At the historic 19th-century observatory, scientists deciphered the composition of the sun and made the first weather forecasts. Today, Sonnenburgh is a museum where visitors can conduct their own research. Climb the stairs to the observatory and wonder at the starry heavens on an Star Viewing Night. Learn all about the unique building, the stars overhead and the weather in one of our exhibitions, tours or lectures. Or take a virtual journey through the universe in the planetarium. Sonnenborgh was built on a monumental 16th-century bastion, and is one of the best-preserved city wall bastions in Northern Europe.
