A city centre (or city center) is the commercial, cultural and often the historical, political and geographic heart of a city.

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.
