Gamla Stan (Old Town).

Dating back to 1252, Gamla Stan is Stockholm’s medieval heart, a compact network of cobblestone lanes and ochre-hued merchant houses spread across a cluster of central islands. Far from a sterile museum district, this preserved core remains the city's active civic anchor. The massive Royal Palace dominates the landscape, flanked by landmark sights like the Stockholm Cathedral, the Nobel Prize Museum, and the Parliament. Beyond the grand institutions, the neighborhood’s real draw is its physical intimacy. You can wander down Köpmangatan, the city's oldest street, or squeeze through Mårten Trotzigs gränd, an alleyway measuring just 35 inches wide. While the main thoroughfares of Västerlånggatan and Österlånggatan are lively with shops and cafés, a turn down any quiet side street reveals centuries of North German-influenced architecture and hidden courtyards.
