It is notable for having been designed by the renowned Finnish architect Alvar Aalto.

[1][2][3] The building is based on Aalto's 1959 winning entry into a design contest for the new Seinäjoki urban plan, and was completed three years later in 1962.

[4] The exterior cladding of the main facade features dark blue ceramic tiles which appear to change colour under different lighting conditions.

[5] The city council assembly hall was designed to serve a dual purpose as a concert venue.

[1] The City Hall forms part of the city's so-called Aalto Centre (Finnish: Aalto-keskus), a cluster of Aalto-designed public buildings and an integral central square,[2] which has been recognised by the Finnish Heritage Agency as a nationally important built cultural environment (Valtakunnallisesti merkittävä rakennettu kulttuuriympäristö).
