This magnificent passage is part of a building named Frestel Palace. Unlike nearby palaces, this palace does not belong to the nobility, but its beauty gave it the title of palace. Frestel is the name of the architect who built it. By the way, he was a talented student of the person who built the opera in Vienna.
Extremely recommend spending two hours in Vienna with guide Tom. He tells the stories of the city and its history in the short, interesting and elegant way. The trip starts from Stephan Platz, passes through the streets of Graben, the Jewish quarter, Am Hof and ends at Ferstel Palace and the Mekler cellar.
