“Devín castle is one of the oldest castles in Slovakia. The castle was likely first mentioned in written sources in 864, when Louis the German besieged Prince Rastislav in one of the frequent wars between the Franks and Great Moravia respectively in the ‘castle of Dowina’. On the other hand, the identification of Dowina with Devín Castle has been under debate based on alleged linguistic arguments and the absence of convincing archaeologic evidence.”
