Stora Nygatan, Pedestrian street in Gamla Stan, Sweden.

Stora Nygatan is a pedestrian zone running through Stockholm's medieval center, lined with traditional buildings featuring detailed facades and stone-paved walkways. The street connects various squares and narrow lanes with restaurants, shops, and public spaces designed for lingering and browsing.

Stora Nygatan was laid out after the great fire of 1625, probably around 1630, as part of Stockholm's first planned street grid. An official attempt to name it Konungsgatan, known from 1637, failed, and the present name was established around 1720. The southern section predates the fire, and by 1660 the street had large stone houses.

The street's name was formalised as Stora Nygatan around 1720 after earlier variants such as Konnungsgatun and den store Nye gatan. At number 19, Gamla Stan Tobak has operated as Sweden's oldest continuously running tobacco shop since 1859. The order Par Bricole, founded after an oration for tavern keeper Gottfried Sack in 1774, still cultivates 18th-century Swedish traditions.

Stora Nygatan runs straight from Kornhamnstorg in the south to Riddarhustorget in the north, parallel to Västerlånggatan and Lilla Nygatan. It is crossed by many narrow lanes, among them Tyska Brinken, Kåkbrinken and Skräddargränd, so it works well as an orientation line through Gamla stan. The surface is flat and paved along its whole length.

At number 2, the Bergstrahl House was built in the 1640s by Erik Ryning, a member of Queen Christina's regency, to designs by Simon de la Vallée. In the 18th century its owner Gottfried Sack ran a tavern and brothel there, visited by the troubadour Carl Michael Bellman; after Sack's death in 1774, Karl Israel Hallman's memorial oration became the starting point of the Par Bricole society.
