RRGC 'Vesslan' is a military bunker located in the Norrköping Municipality of Östergötland, Sweden. Situated near Älggölen and Smedmossen, this bunker forms part of Sweden's Cold War-era defensive infrastructure. The site represents the strategic military preparedness maintained by Sweden during the 20th century, particularly during periods of heightened East-West tensions.
The surrounding forested area of Östergötland provided an ideal location for such installations, offering both natural concealment and proximity to key transportation routes.
