The building was built by Adam Adolf Loewe and Józef Or?owski in 1860. Neo-classicist with eclectic elements, it was designed to shelter the collection of orange trees.
The building was necessary because tsar Alexander II of Russia, who purchased one of the largest in Europe collection of tropical plants from Nieborów, could not transport it to Saint Petersburg, due to climate conditions there. The collection’s pride were long-lived orange trees (there were 124 of them in the collection). Unfortunately, during the World War I, they were left without appropriate care and froze. The building consists of an oblong hall, with glass walls. Today it houses a tropical garden and a restaurant in the northern wing.
