Vienna is known for its magnificent Ringstraße, the expansive Höhenstraße, and the boulevard-like character of Mariahilfer Straße. But off the beaten tourist path, hidden in Vienna’s 2nd district, Leopoldstadt, lies an urban planning curiosity: Tethysgasse. With an official length of just 11 meters, it holds the title of Vienna’s shortest street, thereby eclipsing the prominent Irisgasse in the Inner City in terms of length.

Origins and History
The history of Tethysgasse is closely linked to the urban development around Praterstern and the former Nordbahnhof. It was named on January 18, 1904, by the Vienna City Council. During that era, Vienna was undergoing a phase of rapid expansion and modernization. Amid this construction boom, this tiny thoroughfare emerged, which today is little more than a short connection between Afrikanergasse and Praterstraße. Despite its short length, it is clearly defined as a separate street on the City of Vienna’s digital map.
The naming of the street seems almost ironically grand for such a tiny stretch of asphalt. Tethys comes from Greek mythology and refers to a Titaness and sea goddess, the daughter of Uranus and Gaia. In geological history, the name is also inextricably linked to the Tethys Ocean —a vast ocean that lay between the ancient continents of Laurasia and Gondwana millions of years ago. The fact that an “ocean,” of all things, gave its name to an alley just eleven meters long lends the place a subtle, almost poetic touch. Nevertheless, the naming is no coincidence, but rather a tribute to the scientist Eduard Suess, who lived in the neighboring area.

Tethysgasse, a tiny landmark
Anyone visiting Tethysgasse today will find no monuments or grand facades there . Beyond that, the alley is quite unspectacular. The only thing to do is visit the terrace of the adjacent Pho restaurant. Nevertheless, it attracts lovers of quirky city trivia. A quick blink, and you’ve already crossed it. It is proof that in a city with over 2,000 years of history, even the smallest corner deserves its own place and a name with a ring to it.
