Ole Rømer Observatory

Ole Rømer Observatory is an astronomical observatory and museum, built in 1911 and located in Aarhus, Denmark. It is operated by Aarhus University and functions both as a research and training laboratory for the university Institute for Physics and Astronomy and a museum offering guided tours and lectures. It is named after astronomer Ole Rømer, and the buildings were listed in 2006 as a fine example of Danish art nouveau architecture. The facility also includes a residential house, originally and formerly home to the director of the observatory, today used as a guest house for visiting researchers.

The observatory facilitates education, public outreach and research as part of an original agreement when it was built. The observatory offers presentations and discussions on a broad array of astronomical topics on selected evenings and when the sky is clear the observatory's two 11-inch Schmidt-Cassegrain telescopes are employed.
