Devín Castle

About 15-20km from Bratislava lies Devin castle. It is an incredible rock fortress built on the banks of river Danube. It offers amazing views over the Danube and is one of those places that is definitely worth visiting. You can still see the remains from the 9th century, in the fort in the area, but the current castle was built in the 15th century. In the 19th century, it was ravaged by Napoleon's troops, and its ruins are now part of the museum of the city of Bratislava. You can reach it by boat or bus. I was there in 2006 and there was a bus that you could catch at the river and it took you to the castle.
