Linnanmäki is located in Helsinki, the capital city of Finland, and is a typical city theme park like you find many of in Scandinavia. The park was founded in 1950 and is owned by a non-profit organisation which operates the park in order to raise funds to Finnish child welfare work. In 2016 the foundation donated 4,3 million euros. The park attracts around one million visitors a year and is open from April until October. Admission to the park is free, but you need a ride ticket or an all-in wristband to go on the rides.
