In connection with the renovation and extension of Salo swimming pool, a five-metre colourful beach ball sculpture, Joy, by the sculptor Pekka Jylhä (b. 1955), was unveiled outside the swimming pool on 30 May 2007. The painted stainless steel sculpture was made at Halikko Works. The Halikko-based company had previously worked together with Pekka Jylhä. Part of the President Urho Kekkonen Memorial in Helsinki was made in Halikko.
The sculpture outside the swimming pool serves as a landmark and mascot for the sports park, and creates a positive and happy spirit.
