The Remplin Observatory is the oldest preserved observatory building in Mecklenburg. It is located in the castle park of Remplin. The observatory was built in 1793 by Friedrich II von Hahn and used as an observatory until 1805. The telescopes were among the largest in Europe at the time.
The oldest preserved observatory building in Mecklenburg is located in the approximately 33-hectare Baroque park of the former Remplin estate and castle. In 1793, Friedrich II Count von Hahn had his garden house converted into an observatory. Around 1800, the tower, which is still largely preserved, was built. The final revolving dome was a new type of construction and the applied instruments brought the observatory international attention at that time.
Duke Georg von Mecklenburg-Strelitz commissioned Peter Joseph Lenné to redesign the park after its purchase in the 19th century. Today, in addition to the 18th-century trees, the church and the Baroque gate tower are preserved. The castle fell victim to a fire in 1940. The observatory tower in the north of the park has been lovingly restored for many years. The observatory can be visited on the Open Monument Day.
