Soon after this industrial time another aspect of Tuusulan history was realised. The Tuusulanjärvi lake attracted many artists who wanted to paint the beautiful landscape. Following the footsteps of Aleksis Kivi, the Finnish national poet who spent the last years of his life in a hut on the shores of the lake, Jean Sibelius, Juhani Aho, and Pekka Halonen even established their main residences here. Recently these houses have become tourist sites, especially Sibelius' house Ainola. Also, Tuusula Lake Road on the eastern shore of the lake is an outside museum.
