Tähtitorninvuori - Observatory Hill Park
Tähtitorninvuori (or Tähtitorninmäki) is a 30m high hill next to the South harbour in Ullanlinna district. It's mainly a park but there are also some buildings eg. the Helsinki Observatory from 1834. Observatory Hill Park is known for its wide range of interesting plants. Although the variety of plants has somewhat lessened over the decades, the park is still exceptionally rich in plant life. Almost a hundred species of trees and shrubs grow in the park, as well as many perennials.
