The village of Herttoniemi was one of the oldest in the Helsinge Parish. The Herttoniemi manor is the oldest in eastern Helsinki, and it belonged to the Jägerhorn family already in the 16th century. When Count Augustin Ehrensvärd bought the estate in 1752, the lands of the manor extended to Puotila in the east and to Viikki and Malmi in the north. The area of Myllypuro also belonged to the lands owned by Ehrensvärd. Later, the manor and its lands belonged to Carl Olof Cronstedt, a famous hero of the Battle of Svensksund and the last commandant of Viapori during the Swedish reign. In addition to the Herttoniemi manor, the Ströms manor is also located in this area.
