Linnanmäki also hosts various events and festivals every year, such as the popular iik!week Horror Festival and traditional Carnival of Light (Valokarnevaali), which are both held in the autumn. Mermaid hall Vedenneitohalli (English: Mermaid hall) was one of Linnanmäki's most popular attractions in 1951–1980. Young female mermaid performers, dressed in swimsuits, would lie down on a platform above a pool behind a net. For a fee, visitors tried to hit a release button on a pole at the front of the net with a ball. When the ball hit the target, a lock at the top of the platform would open and the mermaid performer would fall into the water. In the 1970s, men were also being dropped after a women's organisation drew attention to the issue in the name of equality. Naisasialiitto Unioni, a Finnish women's organisation, considered the hall to be a demeaning place for women and in 1978 sent a letter to Linnanmäki's management. As a result, the hall was closed in 1980.
