Mon Repos or Monrepos (Russian: Монрепо́, from the French for "my rest") is an extensive English landscape park in the northern part of the rocky island of Linnasaari (Tverdysh, Slottsholmen) outside Vyborg, Russia.
The park lies along the shoreline of the Zashchitnaya inlet of Vyborg Bay and occupies about 180 hectares (440 acres) of land.
The manor of Monrepos was established by Baron Ludwig Heinrich von Nicolay who bought this parcel of land in 1788.
His wife Alexandrine Simplicie de Broglie (the 2nd Duke's granddaughter) commissioned from Charles Heathcote Tatham an obelisk commemorating her brothers slain in the Napoleonic wars.
The park is noted for its rocks, mostly from the old Wiborgite granite (which is named after Vyborg), and for some glacial formations of up to 20 metres (66 ft) high.
