Explore the rich history of Carnegie Porter, a distinctive Swedish brew that has been delighting beer enthusiasts since 1836.
Tucked between the tall medieval buildings of Gamla Stan, Mårten Trotzigs Gränd is officially the narrowest street in Stockholm. At its tightest point, the alley measures just 90 centimeters wide — so narrow that two people can barely pass each other.
With its 36 worn stone steps, steep incline, and towering facades, the alley feels like a preserved fragment of medieval Stockholm — intimate, vertical, and unexpectedly dramatic.
The alley is named after Mårten Trotzig, a German-born merchant who became one of Stockholm’s wealthiest traders in the late 1500s. He owned property in the area and conducted trade in iron and copper — two of Sweden’s most important exports at the time.
Although the passage existed earlier, it was officially named in the 1940s after centuries of informal use. The alley reflects how densely medieval Stockholm was built — narrow passages maximized space inside the city walls.




Walking through Mårten Trotzigs Gränd feels like stepping into a vertical corridor of history. The tall, closely pressed buildings block much of the daylight, creating a cool, shadowed atmosphere even in summer.
At the top of the stairs, you emerge into brighter streets — a striking contrast that makes the alley feel almost theatrical. It’s this dramatic compression and release of space that makes it one of the most photographed spots in Gamla Stan.
• Visit early in the morning to avoid photo queues.
• Look up — the height of the buildings is part of the experience.
• Combine your visit with nearby landmarks such as the Royal Palace, Storkyrkan, and Nobel Prize Museum.
Mårten Trotzigs Gränd may be small in size, but it offers one of Gamla Stan’s most memorable moments. In just a few steps, you pass through centuries of Stockholm’s urban history — compressed into 90 centimeters of medieval atmosphere. A brief detour, yet a lasting impression.
