Bucharest is the capital city, but also cultural, political and economic center of Romania. It is located on the river Dimbovica in Wallachia. It was the capital of Wallachian rulers since the 17th century and the capital of the whole Republic of Romania is since 1861.
Belgrade is the city that constantly watches over the confluence of the Sava and Danube rivers. Its rich history illuminates it, being the most important transport hub of Southeast Europe and of the Balkan Peninsula. Through the ages it was constantly changing rulers, but never its spirit that can still be testified in the oldest parts of the city.
