The island of Hven or Ven is called "The pearl of Öresund". The island is a popular tourist place in the summer.
Scientist Tycho Brahe was granted an estate on the island of Hven or Ven and the funding to build the Uraniborg, an early research institute, where he built large astronomical instruments and took many careful measurements. After disagreements with the new king in 1597, he left for Prague.
