This squat, square castle, high above the Old Town, is worth the climb to the top, if only for the fabulous view of the space-age bridge, the Most SNP (New Bridge), in the distance. The castle dates from the early 16th century. It burned to the ground at the start of the 19th century and stood as a ruin for almost 150 years before the Communist government started restoration work (still ongoing) in the 1950s. At press time the castle was closed for visitors for ongoing reconstruction and was not expected to open during 2009. You can still enjoy the view from the top -- you'll just miss the castle museum's historical exhibitions which are a bit of a disappointment anyway.
