The Hungarian capital on the Danube, two old cities joined into one: hilly, royal Buda and flat, grand Pest. Climb Castle Hill to the coronation church and the Fisherman's Bastion, walk Andrassy Avenue up to Heroes' Square and the thermal baths of the city park, and read the whole arc of destruction and rebirth in the Jewish quarter of Erzsebetvaros. A city of bridges, boulevards, and bathhouses, made for walking at your own pace.
