The Hanseatic city owes its importance to the Trave, a navigable river, which flows into the Baltic Sea 17 kilometers further north. The old town, located on a hill between Trave and Wakenitz, is one of the finest and most visited in northern Germany and was proclaimed a World Heritage Site by the UNESCO. Lübeck is considered the “Queen” and “Mother of the Hanseatic League” and was the center of power and business on the Baltic Sea during the Middle Ages. St. Marien of Lübeck is one of the main works and the “mother church of Brick Gothic”. Northeast of the church stands a patrician home of the 16th century which belonged to the Mann-family. Thomas Mann will always be remembered by his worldfamous novel “The Buddenbrooks”. Landmark is the massive Holstentor from 1478.
