On the 11 September 2013, the EPS inaugurated the island of Hven as EPS Historic Site. The island is located between Denmark and Sweden.

Bewteen 1577 and 1597, the astronomer Tycho Brahe made his famous observations of the planetary system. During these more than twenty years Tycho Brahe’s observatory on the island of Hven was the most advanced research centre in Europe. The work done there played an essential part of shaping our modern world picture. His detailed notations of the positions of the planets were after Tycho Brahe’s death in 1601 carefully analysed by Johannes Kepler. From this analysis Kepler could formulate his three laws describing the movements of the planets. Three-quarters of a century later Kepler’s laws contributed when Isaac Newton formulated his laws of power.

The place of Tycho Brahe’s observations – on the central part of the island Hven in Øresund between Denmark and Sweden – keeps today a small museum, some rests of the observatory Stjerneborg, and some fragments of the combined renaissance castle and observatory Uraniborg.
