Linnanmäki

Attracting over one million visitors a year, Linnanmäki is Finland's most popular amusement park. It was opened in 1950 and retains much of its old-school vintage charm. Nevertheless, it has been upgraded constantly over the years, and in addition to its many traditional amusement rides, it features modern roller coasters, arcades, thrill rides, activities, restaurants, and games.
The really cool part about the park? It was set up by the non-profit group Lasten Päivän Säätiö (Children's Day Foundation), as a fundraising project for the Finnish child welfare system. Over the years, Children’s Day Foundation has donated over 120 million euros to this important cause.
