A tower built from the bricks of St. Clare's Priory

Standing firmly on the northwest corner of Riddarholmen, Birger Jarls torn remains a steadfast guardian of Stockholm's old defenses. While it pays tribute to Birger Jarl, who is traditionally attributed as the founder of Stockholm, King Gustav I actually commissioned the work around 1530. This monument stands as a rare survivor of a 16th-century defensive system, replacing timbered redoubts destroyed by fire in 1525.

We must look closer at the origin of these materials. For the construction of the tower, bricks were taken from St. Clare's Priory near today's Sergels torg when it was destroyed in 1527, as well as from churches on the ridges surrounding the city. The building was originally two stories high with a crenellated top, featuring a thick cavity wall at the base.

The building has undergone a fascinating evolution that invites deeper study. In 1589–1590, the original crenellation was rebuilt into a third floor topped by a cone shaped roof, and white grouting was added to the façade. During the 18th century, the tower was thoroughly rebuilt, and a fourth floor was added, topped by a new roof with a gilt sphere. By the 20th century, the tower had adapted to various purposes, housing a pawn shop and the city's archives.

In recent years, the tower underwent a meticulous restoration to preserve its historical value while allowing for modern use. Since 2007, the lower level has functioned as a restaurant to make the islet more attractive to Stockholmers. The top floor continues to offer a unique experience as a round conference room where the round windows provide a distinct view of the city.
