about 1405–08. Between 1477 and 1484 Matthias Corvinus had the palace complex reconstructed in late Gothic style. The Italian Renaissance architectural style was used for decoration, the first time the style appeared in Europe outside Italy. After the Ottoman Turks' siege in 1544, the palace fell into ruins. By the 18th century it was completely covered by earth. Its excavation began in 1934 and continues today. The reconstructed royal residence building is open to the public and houses exhibitions on the history of the palace and reconstructed historical interiors. Sibrik Hill The ruins of this military camp can be seen outside Visegrád, to the north, on a hill that overlooks the Danube. The camp has a triangular ground plan. It was built in the first half of the 4th century as one of the important fortifications along the limes, the frontier of the Roman Empire. Its praetorium (the commander's building) was constructed at the end of the 4th century. In the early 5th century, the Roman army abandoned the military camp. In the 10th and 11th centuries, the fortification, rebuilt as a castle, became a regional centre of the recently formed Hungarian state. "Visegrád" appears for the first time as the name of this regional centre (1009). The fortification was finally destroyed in 1242 by the Mongol invasion of Europe.
