Observatory
Evening

The observatory dome at the top of Rundetaarn opens for telescope viewing of Saturn or the Moon on clear evenings. If it is cloudy or raining, observing celestial bodies is not possible, but the observatory's observers are present to share knowledge of the universe, the historic dome, and the telescope for both children and adults. The telescope features a mechanical clock drive to compensate for Earth's rotation. A visit to the observatory is included in regular admission to Rundetaarn.
