Tapulikaupunki is built on the land that belonged to an agricultural research station from 1925 to 1960. When operations ceased began planning what to do with the muddy fields. In the 1970s, a high-rise district with square concrete houses was scheduled high and tight. The designated car parking separated from the houses was a new innovation that enabled the creation of pedestrian areas. The area was first called the high-rise area of Puistola station, but residents quickly began calling area Tapulikaupunki after a road named Tapulikaupungintie that passed through the district. In the 1970s, the name Tapulikaupunki became official. Most of the buildings are from the 1970s and early 1980s. In the 1990s, a new townhouse and apartment block area were built. In the 2000s, modern high-rises along the railway were built. The first residents are getting old and the number of children has decreased. Some day care centers have already been demolished to give way to more high-rise buildings, while others have closed. Many residents feel unsafe around the station due to the presence of rental housing in which drug addicts and people with mental health problems reside. In practice, the area is still safe.

The core idea of Heureka is to "provide the joy of discovery to everyone". Heureka is one of the largest leisure centres in Finland, with about 300 thousand visitors per year. The name "Heureka" (eureka in English) refers to the Greek exclamation, presumably uttered by Archimedes, to mean "I've found it!" (made a discovery). The Science Centre Heureka features both indoor and outdoor interactive exhibitions with exhibits that enable visitors to independently test different concepts and ideas. There is also a digital planetarium with 135 seats. The Heureka Science Centre is a non-profit organization run by the Finnish Science Centre Foundation. The Finnish Science Centre Foundation is a broadly based co-operation organization that includes the Finnish scientific community, education sector, trade and industry, and national and local government. The ten background organisations of the Foundation support, develop and actively participate in the activities of Heureka. The foundation's highest body is the Board of Trustees, whose decisions are implemented by the Governing Board.
