[1] Korkeasaari has been in recreational use for people living in Helsinki for a long time.
Korkeasaari was rented to Helsingin Anniskeluyhtiö in 1883, and the company started renovating the island.
Roads were built and city gardener L. A. Jernström planned planting areas to the island.
In 1972, a bridge was built to connect Korkeasaari to the mainland via Mustikkamaa.
A ferry still operates to Korkeasaari from the Market Square during the summer.
