This manor certainly attracts the attention of every tourist interested in history. It is located just a few minutes' walk from the Helsinki railway station, near the National Museum and the 'House of Finland'. Built in 1846 by statesman Carl Johan Vallgren, the villa became known as the residence of his stepdaughter Aurora Karamzina (Shernval), a well-known public figure and philanthropist, lady-in-waiting, and court lady of the Russian imperial court.

Until 1896, the manor was privately owned until the city purchased it along with the adjacent buildings for 60,000 Finnish marks, allowing Aurora Karamzina the right to live there until the end of her life, which concluded in 1902.

Today, Hakasalmi Manor is a branch of the Helsinki City Museum. It regularly hosts free exhibitions and organizes various displays dedicated to the historical events of the city.

In one of the wings, built in 1847, there used to be a bakery, and now a café operates. Visitors come here to view the exhibitions, stroll through the picturesque English-style courtyard, and find the stone slab under which Aurora Karamzina's beloved dog is buried.
