Kamppi Centre (Finnish: Kampin keskus, Swedish: Kampens centrum) is a complex in the Kamppi district in the centre of Helsinki, designed by various architects, the main designer, however, being Juhani Pallasmaa. It is said to be Helsinki's new downtown commercial and residential centre. As a four-year construction project, it was the largest singular construction site in the history of Finland, involving the extensive and difficult redevelopment of the Kamppi district in downtown Helsinki.
