The ones in the Oberstraße The prevailing narrowness hardly suggests today that city life took place in this street over generations. An example of the magnificent civic buildings built conveniently on the main road is the Engelhardtsche Weinhandlung, the one that is related to The heyday of St. Goar wine cultivation was created. The representative building stands above a powerful cruciform cellar, which provided the ideal conditions for storing the wines. Several other houses on Oberstraße are also former wine cellars.
In addition to the House Engelhardt The Old Market Square of St. Goar, located centrally in the middle of the main street, stretched from the Oberstraße to the city wall. Until the Thirty Years' War, the St. Goar cattle market was held here. With the construction of the railway line from 1857 to 1859, the square was largely destroyed; today only historical cobblestones in the courtyard of the wine shop point to the old St. Goar market square.
