The most famous of the villas’ residents was Princess Zinaida Jusupoff. A villa designed by A.F. Granstedt was built for her in the Kaivopuisto park in 1844. The princess was in residence in the villa during the summers of 1844-6 and 1848 and Prince Jusupoff visited the Finnish capital on numerous occasions. The villa, with 15 rooms and a salon, was also let to Russian guests of the spa.
      According to hearsay, the princess' lover Captain Ishakoff was deported to Finland for insurrection and incarcerated in the jail on the fortress island of Sveaborg.

The princess chose the location of the villa so that she had a view of her lover through the cell window.
      Following the princess Jusupoff, Rauhaniemi passed through several hands. The exterior of the villa was subject to numerous alterations. When the lease was up, some of the parkland was parcelled from the large plot and what remained was divided into three parts. Rauhaniemi was demolished in the 1910's. A villa designed by Jarl Ekelund was erected on the site in 1917, and is nowadays the British Embassy residence.
