Historical orangeries and greenhouses in Poland: typology and preservation

Orangeries and greenhouses were among the most ephemeral buildings erected in Polish gardens. The evolution of technology, the lack of proper maintenance, fires and wars meant that they were subject to constant remodelling or suffered damage. Although they have been an integral part of most garden layouts, providing suitable conditions for the storage and cultivation of exotic plants, to date they have not become the subject of any major academic study. The aim of this paper is to present the results of the first cross-sectional study of historical orangeries and greenhouses in Poland. The research and analysis, carried out in the years 2021–2022, made it possible to identify 165 surviving buildings, for which starting data and a classification by type, material, form, time of construction and architectural style were prepared. Each orangery and greenhouse was subject to an assessment of its degree of preservation using a four-point scale that considered the authenticity and integrity of the historical substance, current use and age. The results of the study can serve as a starting point for identifying conservation challenges in the preservation of historical orangeries and greenhouses and formulating recommendations and standards to better protect these buildings.
