Ever dreamed of spending the night in a 7th century castle on the cheap? If you’re under 27, or traveling with your family, you can! The Burghausen Castle in upper Bavaria, Germany was built in 600 AD and is the largest castle complex in Europe with six courtyards – each with its own gate, moat and wooden draw bridge. While the Dukes of Bavaria once called it home, young travelers can now kick up their feet too, as the castle currently houses 2 museums and a youth hostel. (Click here to book a room!)
