The Private Dacha, also known as the Primorsky Dacha, is one of the notable sites in the Peterhof district of St. Petersburg. Its history begins with the founding of the city, when the emperor gifted this plot to his associate Fyodor Prokopovich. Twenty years after the founding of St. Petersburg, construction of the Primorsky Dacha began, as it was then called. The building was made of stone and attracted the attention of two Russian empresses who visited its owners.

The first owner of the dacha outlived Peter the Great and two empresses, passing away in 1736. After his death, the Primorsky Dacha passed to the 27-year-old Elizabeth Petrovna, who named it the Private Dacha of Her Imperial Majesty, or simply the Private Dacha. The estate existed in its original form until the 1770s, when Catherine the Great ordered it to be rebuilt. She considered the dacha dilapidated and loved to make changes to royal residences, many of which were significantly altered or demolished during her reign.

After Catherine the Great's death, the dacha remained neglected for a long time until Nicholas I gifted it to his heir Alexander. The future tsar, the liberator of peasants and Balkan Christians, fell in love with this estate, spent his honeymoon there, and remembered its decor in the style of Louis XVI. However, he too decided to make changes and commissioned architect Stakenschneider to carry out extensive works. As a result, over six years, the two-story mansion transformed into a neo-Baroque palace with a third floor.

During the Soviet era, the Private Dacha suffered greatly and has not yet been fully restored, but it remains a significant historical and architectural monument.
