In Sweden (to which Finland belonged from the 1300s to 1809), a "Kronomagasin" was a state-administered warehouse in which grain and other foodstuffs collected as tax were stored. Unfortunately, one can't go inside the warehouse any more since today it functions as an office for an architecture company. It is worth checking out from the outside though, the old wooden building sticks out amusingly from the 1980s apartment buildings and offers a reminder of the historical aspects of the city.

Tiedekeskus Tietomaa
Closed for renovation until 2026 The oldest science museum in the country, mostly kinematic and interactive, great for pre-teens but plenty for adults to enjoy. It is partially located in the former Åström leather factory, and you can ride the glass lift up the 19th-century brick water tower.
Oulun Taidemuseo
Two-storey museum with a wide variety of modern artwork. Around 8 exhibits a year. Plenty of information in English, except for small, temporary exhibits.
Hupisaaret, kalatie
The beautiful park of Hupisaaret (lit. Fun Islands) is a lush area with little paths and bridges crossing beautiful little streams. The longest fish path of Finland, 750-m- and 64-stair-long fish path is on the northern part of Hupisaaret park. Take a picnic or just stroll around the renovated park where you can also find the soon-to-be-mentioned Northern Ostrobothnia Museum. Tietomaa and Oulu Museum of Art are also found near the park.
Pohjois-Pohjanmaan Museo
Closed for renovation until 2026A great museum on the history of Northern Ostrobothnia, especially the history of Oulu. Exhibitions on four floors.
Oulun tuomiokirkko
Neoclassical Lutheran cathedral built in 1832 after its predecessor burned down. The architect Carl Ludvig Engel also designed the buildings of Senate Square in Helsinki.
Paska Kaupunki
This iconic graffiti (or at least the nickname which Oulu got from it) is known all around Finland. The term "Paska kaupunki" literally means "Shitty city", and it was adopted from the song with the same name by Kauko Röyhkä. The graffiti appeared on the wall at some point in the 1980s, and after this, the graffiti has been removed numerous times but it has always reappeared on the same spot. The condominium owning the wall has even thought of framing the graffiti or protecting it in other ways since it has become one of the symbols of Oulu. As implied before, this isn't a site funded or even initiated by any official or commercial agent, so the presence of it can't be assured. Although, the drawing or painting of it has become an urban tradition, and if removed, it is almost certainly always remade in some form after a few days from its removal.
