Klasztorne, known at the time by its German name Steineck, has historically been an estate (Gut) under the jurisdiction of Schönfließ (now Trzcińsko-Zdrój). At the turn of the 20th century, the estate, which included a distillery, was owned by Johannes Kühn and encompassed an area of 540 ha (1,334 acres) or 5 km² (2 sq mi). The estate's manor house, which was destroyed during World War II, was located in the western part of the settlement, adjacent to a triangular manor park.^[2]

After the flight and expulsion of Germans from the area as a consequence of World War II, the settlement was given its modern Polish name of Klasztorne. Between 1975 and 1998, Klasztorne was part of the Gorzów Voivodeship.

In the 21st century, Klasztorne is an agricultural settlement primarily composed of privately owned farms. While the original layout of the settlement has been partially erased, many historic buildings from the 19th century, primarily constructed of stone and brick, persist. Some of the historic farm buildings where repurposed as residential spaces.^[2] In 2025, the village had a harvest festival.^[3]

As of the 2021 Polish census, Klasztorne has a population of 99 divided into 53 (53.5%) males and 46 (46.5%) females.^[4] According to the website of the Gmina Trzcińsko-Zdrój, Klasztorne's population was 104 in 2024, an increase of 5.1% since the census.^[5]
