History
The settlement in the Duchy of Austria, located around a medieval castle at the site of the former Roman camp of Carnuntum, was first mentioned in 1297 and received market rights in 1579. The prefix Deutsch- was added to differ it from nearby Altenburg (Óvár) in Hungary. From 1916/17, it was the site of a large longwave and high frequency radio transmitter station, which was dismantled in the 1980s.
In March 1945, numerous Jewish forced labourers were deported on a death march from the south-east wall to Bad Deutsch-Altenburg, where they had to embark up the Danube to Mauthausen concentration camp. A memorial stone marks the site of a mass grave, where exhausted prisoners shot by the security forces were buried.Eleonore Lappin: Die Todesmärsche ungarischer Juden durch Österreich im Frühjahr 1945.
