[8] In 1957, the welfare organisations formed the non-profit Children's Day Foundation, which continues to manage and develop the amusement park.

Although the towers were disconnected from the water grid in 2003 and are no longer operational,[9] they are protected by the city's zoning plan and cannot be demolished.

The newer, cylindrical tower, which dominates the park and its surroundings, houses an indoor roller coaster called Linnunrata eXtra.

Since its opening in 1950, Linnanmäki has had two fatalities related to ride accidents, both involving the Vuoristorata roller coaster and resulting from rider negligence.

[10][11] The first incident occurred in 1953 when the roller coaster's brakeman, who had finished his shift, sat in the front row for the final ride of the evening.

In 1985, a young male guest sitting in the front row managed to open the safety bar and stood up to wave to his friends.

[10][11] Linnanmäki is situated in the Alppila sub-district of Alppiharju, 2.5 km (1.6 mi) north of Helsinki's city centre, the capital of Finland.

The park has no distinct theming and feels relatively compact and densely packed, with rides and attractions in close proximity to each other.

Beyond the amusement rides and attractions, the park is home to the Peacock theatre, a historic venue built in 1957, renowned for its musical productions.

From 1996 to 2005, the park also housed Linnanmäen museo, a museum facility near the main entrance that hosted several exhibitions annually.

[14] Separate priority boarding tickets are also offered for Taiga and Swingi, allowing riders to skip the line through a dedicated entrance.
