Stjerneborg, Underground astronomical observatory on Ven island, Sweden
The observatory contains five circular chambers built below ground level, connected by corridors and equipped with astronomical measurement instruments.
Tycho Brahe constructed Stjerneborg in 1584 as a supplementary facility to his main observatory Uraniborg for enhanced astronomical observations.
The observatory demonstrates 16th-century scientific methods through preserved instrument foundations and detailed architectural reconstructions of observation platforms.
Visitors can experience the observatory from May through September, with guided tours explaining the astronomical instruments and underground chambers.
The subterranean design protected sensitive astronomical instruments from wind interference, enabling more precise measurements of celestial bodies.
