The ruins of King Valdemar the Great's Vordingborg Slot have been given new life with the opening of the Danish Castle Centre, a high-tech museum exploring the castle's history, as well as that of medieval Danish power, politics and castle life. Using interactive iPads, visitors can explore themes such as the tactics used by kings to gain and retain power, as well as learn about the museum's historical artefacts. Among these is an extraordinary piece of 15th-century chainmail armor, weighing almost 11 kilograms.
Outside, the iPad guide brings the ruins back to vivid life with digital reconstructions, while dedicated kids' features allow little ones to 'hunt ghosts' among the ruins. Scan your museum ticket to enter and ascend the Gåsetårnet (Goose Tower), the only surviving remnant of what was once a mighty fortress.
