City Park Hupisaaret Island public urban park in Myllytulli district in the center of Oulu, Finland . The park is located in the Oulu River Delta. The area was built as a public park in the 1860s, at the same time were built the first white wooden bridges characteristic of the park.
Small streams and waterways divide the park zone into smaller and larger islands. The largest islands are Platansaari, Pakolansaari, Paratijisaari, Kiikkusaari and Lasaretinsaari. The name Hupisaaret used to be used only for a group of numerous nameless small islands in the northern part of the park, but later the entire park zone was named after these islands.
The Museum of Northern Ostrobothnia has been located on Pacolansaari Island in the park since 1911. The first museum building, a national romantic villa, was built in 1888, but burned down in a fire in 1929. The current building was designed by the architect Oiva Callio. It was completed in 1930.
