The political ideology, involving the attributes of the single party system, and the prevailing economical conditions, reflecting the state socialism approach, had important influence on the changing understanding in architectural expression. These reflections concern both the inclusion of the Culturepark in the urban design of izmir and the temporary pavilion buildings designed and constructed for the izmir International Fair.
