The door of this house is located in the historic center of Speyer, which has so many buildings with landmark status that it has declared entire streets to be a "landmark zone".
The door has it's own address Kleine Pfaffengasse 25 although it is physically located in the Judengasse. The door opens directly onto the street as you can tell by drainage and cobblestones in the foreground as well as in the next photo.
The house is located at a cultural crossroads between Catholism, Judism and Protestantism. Nearby is the bishof's residence and the Catholic Diocese, one of the oldest in Germany, dating back to the 4th century. The Judengasse (Jewish alley) leads to the ruins and museum of the former Jewish Quarter also dating back to the 4th century. One block away is the Lutheran Protestant Church Council.
