Once up, a magnificent view over the Danube river and the Pest side of Budapest unfolds from Castle Hill. This lively area breathes history and is stuffed with interesting cafes, stores and museums. The most prominent building is the Royal Castle, the seat of the former Hungarian rulers, and now housing the Hungarian National Library and several museums. The Hungarian National Gallery is worth a visit, showing collections dating back as far as the 10th century. After your visit to the Royal Castle, we suggest you to just wander around the area. Winding cobbled streets and leafy promenades will lead you past Baroque cottages, Habsburg monuments and cafes such as the early 19th-century Ruszwurm where you can enjoy a classical Hungarian pastry, originally made from cooked egg cream with vanilla mixed with egg white. However, the Ruszwurm pastry is not mellowed with egg white but with whipped cream. Mjum!
