Vác is one of the stops on the very scenic day trip to the Danube Bend region. It's a pretty little village with a fine cathedral and a small castle. When they renovated the cathedral in 1994, they stumbled upon a closed vault which hold a huge number of mummies. It turned out they were from 17th century and as they were very well preserved, they gave the historians an insight into middle ages Hungary. Today some of the many mummies are on display in the museum across the square from the cathedral.
