The orangery is the most important surviving part of the Blieskastel castle complex. It was completed in 1670 and originally had twelve axes, which characterised the long side of the building. The ground floor was used to store orange trees and other fruit that liked it a little warmer in winter. The arcades, which were still open at the time, were clad with wood for this purpose. Before the building was first referred to as the "Orangerie Gebäud" at the end of the 18th century, it was used as a playroom and parlour for the von der Leyen family and their guests. Today, the building is one of the most remarkable relics of 17th century German architecture in Saarland.
