Volkssternwarte Rothwesten, Public observatory in Rothwesten, Germany

Volkssternwarte Rothwesten is a public observatory housed in the wooden dome atop the 300.7 m Häuschensberg observation tower above Rothwesten in Fuldatal. The copper-clad dome, assembled on a meadow below the hill and hoisted up in two halves by winch, holds three telescopes: a 210 mm Newton reflector built by Georg Spitzer, a 300 mm reflector for faint galaxies and nebulae, and a 127 mm Meade ED APO refractor for sunspots.

Georg Spitzer planned a public observatory from the 1950s; on the initiative of Rothwesten mayor Fritz Kranke it was placed on the Häuschensberg, where a lookout tower had collapsed after 1912. The tower was built from 1959 and finished in 1962. The wooden dome, clad in copper, was assembled on a meadow below and hoisted up in two halves by rope winch after the planned helicopter lift fell through during the Cuban Missile Crisis. It opened on 15 September 1963.

This observatory functions as a public space where people can engage with astronomy and use professional telescopes to observe the night sky. The facility welcomes visitors who want to deepen their understanding of celestial objects and share the experience with others.

The observatory sits atop the 300.7 m Häuschensberg, above the Rothwesten district of Fuldatal, on the tower whose top floor holds a walk-in camera for 5 to 6 people. Access is via the hill; the copper-clad dome and tower facade were renovated in 1991, 2005 and 2012. Guided tours and events are offered; check the weather before a night visit.

The observatory features a walk-in pinhole camera that functions as a spectroscopic laboratory, offering visitors hands-on insight into optics and light behavior. This interactive element allows people to understand camera mechanics and light spectrum through direct experience.
