Stjerneborg

Stjerneborg was Tycho Brahe's underground observatory next to his palace-observatory Uraniborg, located on the island of Hven in Oresund.

Tycho Brahe built it circa 1581, when he found Uraniborg neither stable nor large enough for his precision instruments. He named it Stellaburgi in Latin. Both the Danish and Latin names mean "castle of the stars".

The underground portions of the observatory were excavated in the 1950s and are today fitted with a roof approximating a multimedia show open to the public.
