The land in Roihuvuori once belonged to Herttoniemi Manor. Herttoniemi and Roihuvuori (then known as “East Herttoniemi”) became part of Helsinki in 1946. There is a strong sense of community within Roihuvuori, or “Roihis” as it is familiarly known. In 2010 it was named “District of the Year” by the Finnish Local Heritage Federation.
