Łańcut Castle Orangery (Oranżeria)

The Łańcut orangery was built between 1799 and 1802 on the initiative of Princess Izabela Lubomirska, to house orange trees transferred from Wilanów. The design is by Christian Piotr Aigner, with the stucco executed by Fryderyk Bauman. The building served as a heated winter garden where guests came to stroll; the plants that overwintered there were taken outdoors in summer. It also hosted concerts, theatrical performances and receptions.

Under Roman Potocki and Elżbieta, née Radziwiłł, the building was thoroughly renovated and its interiors remade between 1889 and 1912. After the war it housed the Arkona club, with a reading room and lectures; in the 1960s it became a winter garden again, with exotic plants and animals. Structural works followed in 1952-1960: wooden ceilings were replaced, mezzanines created in the north wing, staircases renewed and the roof changed from a sunken form to a gabled one.

Between 2018 and 2020 a major renovation added cellars under the whole building, costing nearly 32 million zlotys, 22 million of it from European funds. The works uncovered two brick furnaces and heating channels, fragments of pottery and tiles, wall paintings and a timber structure believed to be a former powder magazine. The building became the Jan Potocki Centre for Education of Tradition.

The orangery is a classical two-storey pavilion, crowned with an attic and covered by a gabled roof. The west elevation is decorated with a four-column Ionic portico; to the east an arcade links it to the castle. The south façade has eleven bays, with large semicircular windows and wooden trellis work, while banded rustication and a cornice articulate the elevations. The ground floor held an orangery hall; the upper floor originally contained rooms and wardrobes.

Excavation during the renovation revealed underfloor heating: two furnaces and channels that distributed warm air, together with western chambers where fires were kept. These remains show how the volume was heated to preserve the plants. The works of 2018-2020 added cellars beneath the whole building, and the interiors now host multimedia presentations.

In the nineteenth and twentieth centuries the castle's gardeners grew citrus (bitter and sweet oranges, lemons), rhododendrons, camellias, magnolias and cypresses here, carried out onto the terraces in summer. Period inventories also mention laurels, azaleas and palms across the castle's glasshouses as a whole.

Today the building no longer holds a living collection: its two floors present multimedia exhibitions on the castle's history, garden styles (Renaissance, baroque, romantic) and the travels of Jan Potocki, including a virtual balloon-ride installation over Łańcut. The plant tradition is carried on by the neighbouring orchid house: 640 m², of which 230 m² for display, with tropical, warm, temperate and cold zones; the cattleya, the Potockis' favourite orchid, dominates, and historic specimens survive.

The orangery stands in the grounds of Łańcut Castle, linked to the main building by an arcade; it is visited together with the rest of the castle museum, including the 36-hectare landscape park, the Italian, rose and perennial gardens, and the collection of horse-drawn carriages. About an hour should be allowed.

The orchid house, built around 1904-1908, has been open to the public again since 2008 and shows its orchids from October to March, flowering usually concentrating in October and November. It combines naturally with a visit to the orangery.
