Leevaku Chimney, which is joked about as being the world's tallest sauna chimney (at 50 metres), was completed in 1923 for the local brick factory. However, the factory soon went bankrupt, as the raw ingredients being sourced locally were of insufficient quality.
After the factory closed, the owner of the neighbouring residence built a wooden sauna in the chimney, and it is still used today.
The chimney can only be viewed from the outside.
