A historicist garden masterpiece

The overall design was created by the Prussian garden director Peter Joseph Lenné, who combined several European garden styles into one composition: a Baroque parterre, a water cascade recalling Italian Renaissance gardens, and broad areas in the style of English landscape parks.

Festival hall & glasshouses

At its heart stands the palatial glass-and-iron winter garden, modelled on the Paris Jardin d'hiver and London's Crystal Palace. The hall still hosts events today, while the glasshouses present tropical and subtropical plant worlds.
