The Keskuskatu street is lined by the Linden Esplanade of approximately 800 metres. The first trees in the esplanade were planted in the 1800s.
The trees were planted because fixed points and eye-catchers were required in the boulevard. The conversion of the Linden Esplanade into a Sculpture Promenade was a solution that brought life and tension to the townscape. The objective was to create a versatile park which enriches the townscape and presents mainly Finnish high-quality sculptures.
