The
City-Center was a plan to raze and rebuild the block between the central
Helsinki streets of Kaivokatu, Keskuskatu and
Aleksanterinkatu, creating a unified, modern appearance for the area. The plan was originally drafted between 1958 and 1960 by
Viljo Revell; Heikki Castrén continued work on the plan after Revell's death in 1964. The fulfillment of the plan would have required the demolition of several old buildings that are today considered to be a vital part of Helsinki's heritage.
