In the early years, the center, built by Polar-Yhtymä construction company, had interior
waterfalls and customers could play
tennis on two outdoor courts built on the roof during the summer. In 2018, Finland's largest
LED display was built on the roof of Koskikeskus. The
octagonal "crown" has an area of 144 square meters and weighs 2,390 kilograms. In May 2019, Koskikeskus invited teenagers who were in the mall a lot to come up with common rules for a workshop organized by the Nuorten Palvelut
youth service. The rules are available for everyone to see in the mall's
information kiosks. == Services ==
