Lustiga Huset is the amazing fun house at Grona Lund. Originally built by the park in 1917, this walkthrough was refurbished by Zierer in 1987. This attraction features multiple moving platforms, mirrors, and slides!
Reminds me alot of the old of Vekkula, the old fun house in Linnanmäki that had to be removed in 2017 to make room for Taiga's station area. At the time of it's removal it was one of the oldest attractions at the park, being build 1961. It was also a lot of people's favourite and many were disappointed about the removal of such a classic attraction. Among other things, Vekkula had a similar 45° angled room, rotating tube hallway, moving stairs and the final carpet slide seen in this video.
