Långholmen, Stockholm Travel Guide

Långholmen, meaning 'Long Island,' sits in Riddarfjärden bay between Södermalm and Kungsholmen, serving as a key stop for ships from Lake Mälaren into Stockholm. For centuries, its uninhabited rocky terrain made it a strategic military camp, especially during 15th- and 16th-century battles and the Russo-Swedish War of 1788–1790. Donated by Queen Christina to the city in 1647, it hosted a suburban farm and, from 1685, Mälarvarvet shipyard on the eastern end—a facility still operational today under city ownership.

In 1724, the city acquired the Alstavik farm to establish Långholmens spinnhus, a women's prison amid 17th-century famines that drove beggars to the streets. Women spun wool there until 1825, when operations shifted, and male prisoners took over with tasks like shoemaking, carpentry, and operating pedal-driven mills. Expanded in the 1800s, it reached 950 inmates. The grand Centralfängelset, built 1874–1880 by architect V. T. Anckarsvärd, boosted capacity by 300, introducing basket weaving and printing. It housed over 500 cells as Sweden's central prison until temporary closure in 1972–1975, fully ending in 1975.

Originally stark and rocky, Långholmen was transformed by 19th-century inmates who dredged mud from surrounding waters to create soil. This fertile layer sprouted lush gardens, infused with exotic seeds carried by merchant ships, yielding a unique flora distinct from mainland Stockholm. Today, this 'Green Island' boasts verdant paths, meadows, and woodlands, a peaceful contrast to its penal past. Preservation efforts post-closure saved key structures from demolition, honoring 250 years of history as advocated by antiquities experts.

Långholmen holds dark milestones: site of Sweden's last execution on November 23, 1910, when Johan Alfred Ander met the guillotine at 8:06 a.m. for murder. Notable inmates included journalist Barbro Alving, author Jan Guillou, and activist Zeth Höglund. A plaque marks the execution spot, and a prison museum in the main building displays artifacts, original cells, and even uniforms for visitors. The complex, partially demolished in 1982, now includes a folk high school.

Since 1989, the prison buildings host a 112-room hotel and hostel, renovated in 2007–2008, with cells converted to cozy accommodations—keycard access replacing iron bars. Guests enjoy breakfast on outdoor terraces overlooking beaches lively with summer swimmers and picnickers. Trails wind through gardens, past the overgrown Karlshälls Gård estate tied to the 1870s 'aquavit war,' and 'Fördärvet' pub site. Långholmen Football Club, founded in 2002 by expats, thrives on the gravel pitch, fostering community.

Accessed via Pålsundsbron (east) and Långholmsbron (west)—the latter rebuilt in steel in 1931 after wooden predecessors—Långholmen blends history and nature. A 1993 JAS 39 Gripen crash during the Water Festival left a stainless steel paper plane sculpture by Thomas Qvarsebo. This oasis remains a cherished retreat, its paths echoing from battles to incarceration, now alive with walkers savoring the island's improbable verdancy.
