The Yellow Tower is an observation tower on the "Spitzhut", part of the Vorholz ridge in the southeast of Hildesheim.
The tower was built in 1886 to mark the completion of the reforestation of the Vorholz ridge. Its name is derived from the building material used - yellow bricks were used. Since then it has served as a popular destination and observation tower for walkers in the Galgenberg.
After many years of use, the tower had become dilapidated and the entrance to the tower was blocked off. The intention of the Hildesheim building administration to remove the tower once and for all led to the founding of a citizens' initiative in 1996 - the Association for the Rescue of the Yellow Tower. Thanks to donations from Hildesheim citizens and companies, a comprehensive renovation of the tower was possible.
In addition, a public observatory was built on the tower as a metal structure, which is visible from afar. The 60 cm mirror telescope comes from the Leibniz Institute for Astrophysics in Potsdam and was transported to Hildesheim by helicopter on August 19, 1999. It is the largest mirror telescope in southern Lower Saxony. The observatory was initially open to visitors under the direction of the Hildesheim adult education center. Since 2011, the Hildesheim Society for Astronomy has operated the observatory and offers public observation sessions for up to 25 participants every Friday evening.
