An illuminated merry-go-round at Linnanmäki, Helsinki's most popular amusement park in late October during the annual Linnanmäki lights carnival. The lights carnival is Linnanmäki's annual closing event, lasting for a week, where numerous rides and other places at the amusement park are artistically illuminated with bright, coloured lights in the evening. The event itself is free of charge but there is a fee for going on any of the rides.
