Mon Repos or Monrepos is an extensive English landscape park in the northern part of the rocky island of Linnasaari outside Vyborg, Russia. The park lies along the shoreline of the Zashchitnaya inlet of the Vyborg Bay and occupies about 180 hectares of land.
The manor of Monrepos was established by Baron Ludwig Heinrich von Nicolay who bought this parcel of land in 1788. The estate was considered a jewel of Old Finland and belonged to his descendants until the Soviet takeover in 1944. The core of the baronial estate consists of the Neoclassical main house and the library house.
