The fountain-dotted Mittlerer Schlossgarten draws thirsty crowds to its beer garden in summer. The Unterer Schlossgarten is a ribbon of greenery rambling northeast to the Neckar River and the Rosensteinpark, home to the zoo. Sitting south, the Oberer Schlossgarten (Upper Palace Garden) is framed by eye-catching landmarks like the columned Staatstheater and the ultramodern Landtag, a glass rectangle housing the state parliament.
