Museum in Maria Taferl & Artstetten

Built from the ruins of a 13th-century medieval castle and tinkered with for 700 years, this castle gained fame and glory after passing into the hands of the Habsburgs in the early 19th century, winding up in the possession of Archduke Franz Ferdinand. Inside is a museum devoted to the luckless heir, displaying photos and stories of his and his wife’s lives at the castle and their fateful trip to Sarajevo where his assassination kicked off WWI.

About 6km east of Maria Taferl and about the same distance off the Danube.
