The Plenipotent's Palace (Plenipotentówka) is a Swiss-style villa built between 1880 and 1890 for the Zamoyski Ordynacja. It has a stone foundation, a brick ground floor, and a timber-framed upper storey and wings, with decorative wood panelling and carved details. A cobbled drive leads through a covered wooden gate; the grounds include an 1885 stable, a wooden well, and a garden.

The residential complex was built between 1880 and 1891 during a period of regional development. A stable and wooden well were added shortly after, becoming part of the overall property structure.

The palace now serves as the administrative headquarters for Roztoczański National Park while remaining a protected architectural landmark. You can see how the building continues to function as a working center while people respect its role in the region's heritage.

The building is accessible as the park's administrative center and serves as a starting point for exploring the surrounding landscapes. Information about trails and natural attractions in the area can be obtained here before venturing into the park.

The complex grew in stages: a wooden well and stable date from 1885, an ice house was added in 1905, a new fence in 1906 and a greenhouse in 1908. The entrance gate carries the inscription "Roztoczański Park Narodowy".
