Söderbergs trappor, Historic staircase in Södermalm district, Stockholm, Sweden

Söderbergs trappor is a stone staircase on Södermalm in Stockholm running from the corner of Katarinavägen and Renstiernas gata down to Stadsgården. Its 144 steps make it the longest staircase in the city's inner districts. The present flight was built in the early 20th century alongside the blasted rock face, parallel to the cliff.

In 1750 the plot at the end of Högbergsgatan belonged to stocking weaver Anders Söderberg; the land passed to knitter Ulrik Söderberg and then to stocking manufacturer John Söderberg, who made his fortune selling wool comfortables. One of these Söderbergs built a wooden staircase along the plot's eastern side, running from Stadsgården up to what was then Katarina östra kyrkogata. Around 1900, when Stadsgården was expanded and parts of Stigberget were blasted away, the stairs were rebuilt in stone beside the new rock face.

The staircase connected dock workers and residents across different neighborhoods, serving as a key passage through the steep terrain of the southern district. It reflects how people moved through and shaped this part of the city over time.

The staircase is accessible year-round from multiple entry points throughout the district without restrictions. Take care when climbing after rain or during winter, as the granite surface can become slippery.

The stairs serve as a popular training spot for runners and athletes who regularly use the 144 steps for conditioning work. This everyday activity has turned the location into an informal fitness hub within the urban landscape.
