 All these buildings had been the result of open architectural competitions.A more direct connection between Aalto and the somewhat opposing trend of Structuralism can be seen in the work of Arto Sipinen; he had been an employee of Aalto at the time when the latter was directing the construction of the Seminaarinmäki campus for the University of Jyväskylä (1951–1969).Aalto had resigned from planning of the area in 1969 following disagreements with the clients and consequently a competition was held in 1969–70 for the further planning of the campus, including a new main library.
