Danube Land Donauland

South of the Marchfeld lies the Donauland ("Danube Land"). Bad Deutsch-Altenburg, on the right bank of the Danube near the site of the Roman Carnuntum (see Petronell/Carnuntum), has a strong sulfur spring which was already being used for medicinal purposes in Roman times and still attracts visitors to the spa. A short distance to the southwest of Deutsch-Altenburg lies Rohrau, the birthplace of Joseph Haydn, and the castle of the Harrach family, with one of the richest private collections of paintings in Austria.
