There's a scale model of the Solar System in the Toijala centre. It is in 1:3.000.000.000 scale so all the planets are found in Toijala, but Voyager 1 has gotten as far as Viiala. It includes Proxima Centauri, which can be found in Yulara, Australia.
Akaa Solar System Scale Model is located at the center of the city of Akaa, Finland. The Sun is located at the school campus of Toijalan Yhteiskoulu in Toijala district. The scale of the model is 1 : 3000000000, meaning that each centimetre in the scale model represents 30000 km in real life. The Sun is 464 mm in diameter and the Earth is 4 mm in diameter and located 49.86 meters away from the Sun. Neptune is 1500 meters away from the Sun, for example. Akaa Solar System Scale Model was built in 2017 by amateur astronomer Kari-Pekka Arola.
A collection of Finnish state railways' rolling stock, including two operable steam locomotives and several operable diesel locomotives. Check the website for special events such as running days.
An operational wallpaper factory doubling as a museum. Oldest machines from the 19th century. A factory outlet shop is open throughout the year.
A museum displaying traditional Finnish rural lifestyle and associated items. A highlight would be the collection of more than 40 different wooden shovels. The location link is correct, OpenStreetmap is just missing a road here.
A collection of more than 300 different baby carriages in the oldest surviving house of the town of Viiala: the Toorikka manor main building. Oldest carriages are from the 1870s.
A large (by Finnish standards) neo-Gothic wooden church built in 1817. The tower was modified in the late 19th century. Altarpiece from 1881, ceiling paintings from 1935.
The first church built in Finland after World War II, opened in 1950. Built almost completely on donated money and materials. The concrete used was mixed with cement donated by American Lutheran congregations. Interesting altarpiece depicting Christ in Viiala town.
