Basilikenhaus, Vienna — Visitor Guide & Things to Do Nearby

On June 26, 1212, something terrifying was discovered in the well of baker Martin Garhiebl's house. A mysterious creature with a poisonous breath lurked in the depths, and the people of medieval Vienna identified it as a basilisk, a legendary beast said to be born from a rooster and a toad. The story became one of Vienna's most enduring legends, and the building where it happened still stands today, known as the Basilikenhaus.

Modern science offers a more practical explanation. Toxic earth gases likely accumulated in the well, creating an eerie phenomenon that the medieval imagination transformed into a mythical monster. But the legend was too good to let go. In 1577, bookseller Hans Spannring placed a commemorative plaque on the building during renovations. That plaque eventually disappeared, but when the house was restored in 1932, a fresco was added to the facade depicting the terrifying creature and its story.

The Basilikenhaus features a Gothic facade and ranks among the oldest surviving structures in Vienna's 1st district. Its exterior is worth a pause for anyone who enjoys the intersection of history and folklore. Look up and you will see the 1932 fresco keeping the basilisk's memory alive on the building's face.

Vienna is full of hidden legends like this, tucked into ordinary-looking buildings on quiet streets. Discovering them is half the fun of exploring the city. A Questo quest through Vienna's historic center connects you with stories like the basilisk, turning a simple walk into an adventure filled with myth, mystery, and a healthy dose of medieval imagination.
