The character of Dracula, as created by Bram Stoker in his novel "Dracula", is fictional. While the novel draws inspiration from historical figures and locations, there is no actual palace associated with Dracula.
However, Bran Castle in Transylvania, Romania, is often associated with Dracula due to its dramatic appearance and its historical connection to Vlad the Impaler, a 15th-century Romanian prince who inspired Stoker's character.
While Vlad the Impaler likely never resided in Bran Castle, it's a popular tourist destination and has been marketed as "Dracula's Castle" for decades.
