Have you noticed the small markings to the left of the main entrance to St. Stephen’s Cathedral? Right next to the famous Giant Gate, centuries-old notches are carved into the wall, telling stories of medieval swindlers, strict inspections, and a persistent Viennese myth . Anyone who shopped at Stephansplatz in the Middle Ages could put the goods through their paces right here. But what’s really behind the metal rods and the engraved circle? We set out to uncover the truth.
Tangible Trade Control: What the “Tuchmaß” Is All About

The two iron rods are genuine historical units of length—the so-called “Tuchmaß”—dating from the 15th century. The shorter rod measures exactly 77.6 centimeters and represents the Viennese “Tuchelle,” while the longer one, at 89.6 centimeters, served as the “Leinenelle.” Back then, if you bought fabric at the market and didn’t trust the merchant, you could check the bolts of cloth directly against the church wall. The location at the cathedral was ideal, as the church was considered a public sanctuary and guaranteed accurate measurements.
The Legend of the Bread Measure—and What’s Really Behind It
Right above the cloth measures, you’ll notice a deep circle carved into the stone. For generations, local legend has claimed that bakers had to check the size of their loaves here. However, that’s pure Viennese folklore! In reality, these are simply scuff marks left by an old Rococo lattice gate that sealed off the entrance until 1880. With daily opening and closing, the iron fastening hook repeatedly scraped against the same spot on the facade, leaving behind this perfect circle.
Bakers’ Shacks: How Cheating Bakers Were Brutally Punished

Even though the circle wasn’t a measure for bread, the Viennese took no nonsense when it came to bread that was too small or of poor quality. Anyone who cheated on the weight or used inferior flour was subjected to the infamous “Bäckerschupfen.” The fraudulent bakers were locked in a wicker basket and dunked several times into the cold waters of the Danube in full view of the mocking crowd. A humiliating punishment that wasn’t abolished until the 18th century.
