Ruisrock is a rock festival held annually on the island of Ruissalo in Turku, Finland. Ruisrock, founded in 1970, is the second oldest rock festival in Europe and the oldest in Finland. The festival has attracted world-famous artists throughout its lifetime except in the turn of the 2000s, due to the organizer's economic issues. There are plans to expand the festival area, from the five stages currently present.
The festival area is divided into two sections, Niittyalue ("meadow section") and Ranta-alue ("beach section").
In 2005, when the German industrial metal band Rammstein performed at the festival, 71,000 visitors attended the festival. In recent years, the number of visitors has fluctuated around 70,000. However, the all-time record was set in 1971, when there were about 100,000 visitors, with artists such as Canned Heat playing.
The 2009 edition of the festival saw a rise in attendance, when during 3 days there was a total of 92,000 visitors. In 2009, musical acts such as Slipknot, Disturbed, Faith No More, Mew, In Flames, Volbeat, Glasvegas, The Sounds and popular domestic artists including Children of Bodom, HIM, Eppu Normaali, Tehosekoitin played at the festival, including the last live performance by The Crash.
In 2010, the festival was celebrating its 40-year anniversary, with popular artists such as Slash and Ozzy Osbourne playing.
