Observatorium Tusculanum

The observatory structure measures 5.5 meters by 5.5 meters and includes a floor design lowered by one foot to minimize interference during observations.

Ole Rømer established the Tusculanum Observatory in 1704, selecting this location away from Copenhagen to conduct astronomical measurements without urban disturbances.

The name Tusculanum derives from Cicero's villa near Rome, reflecting the intellectual connection between astronomical research and classical scholarship in Danish science.

Visitors can view the preserved foundation markers and Ole Rømer statue at the site, which connects to the Kroppedal Museum's exhibition program.

The observatory contained the world's first meridian circle instrument, four astronomical clocks, and maintained communication with Rundetårn through night light signals.
