Der Hauptmarkt

The Hauptmarkt of Trier is the central and one of the largest squares in the city.
It is located in the historic city center directly in front of the cathedral city in what is now the district of Mitte/Gartenfeld. The most important shopping streets of the city meet here. In 958 Archbishop Heinrich I furnished the main market with the market cross as a symbol of sovereignty. The main market was a place for selling goods and trading in the medieval town.Two-thirds of the market surrounds with houses from the Renaissance, Baroque, Classicism and late historicism have been preserved. Today, numerous large and representative buildings are characteristic of the city, including the Hauptwache and the former cathedral hotel in the Neo-Renaissance style of German origin. There is also the Steipe, a town house built around 1430 and (after it was completely destroyed in World War II) rebuilt in the 20th century with the help of "creative monument preservation" (Dehio) and today the representation house of the city council as well as the Red House with the saying about the legendary founding Triers through Trebeta. The church of St. Gangolf is only accessible from the market through a baroque gate and is otherwise completely rebuilt.From the main market you can step through the Judenpforte into the Judengasse and get into the former Jewish quarter of the city.
