• A sculpture you can enter, so kids can walk in under the pipes and hear the echoes and sounds the structure makes
• The Sibelius bust sits on one side of the pipes, a face for kids to hunt for; Jean Sibelius (1865-1957) is Finland's best-known composer
• One of Helsinki's best-known sights, so expect other visitors around the pipes while the rest of the park stays wooded and rocky

Sibelius Park is a stretch of woods and rugged rock in Töölö, home to Eila Hiltunen's Sibelius Monument. The sculpture is over 600 welded steel pipes, 8.5 meters high, shaped like organ pipes, with a bust of the composer Jean Sibelius on one side.

It is built so visitors can step inside it, and kids can listen to the echoes and sounds the pipes make.
