The historic park in Lancut was established in the late 18th century. Its greatest heyday came at the turn of the 19th and 20th centuries, when Roman and Elzbieta of Radziwill Potocki became the owners of Lancut.
At that time, the park was redesigned and almost doubled in size by attaching a large area on the east and west sides.

In the immediate vicinity of the Castle (within the moat), several new garden "interiors" characteristic of the period were created. The main avenue leading from the western bridge to the Castle received a setting of four yew trees cut into a cone and rectangular elongated beds planted with summer plants.

A regular rose garden was established in front of the south elevation of the Orangery, and a perennial bed in front of the newly built Outbuilding. The area in front of the Castle's eastern elevation was decorated with an Italian garden. Already beyond the moat, on the line between the Dressage House and the Castle, a Palm House modeled on those in Vienna (dismantled after World War I) and greenhouses for growing, among other things, orchids were erected.

The rest of the park was laid out in the style of an English landscape park with freely routed avenues among extensive lawns and planted with various species of trees and shrubs. Such a compositional arrangement, together with an age-old stand of trees, thanks to a number of revaluation works, has been preserved to the present day and constitutes a unique historical and natural value.
