The notorious former headquarters of the KGB in Riga, Latvia is now open to the public, leaving a reminder of the terror propagated by the agency during the Soviet rule.
The KGB (which translates to Committee for State Security) was the Soviet Union's secret police, functioning as foreign intelligence and counter-intelligence, as well as combatting dissent and anti-Soviet activities.
The KGB monitored public and private opinion in all of the countries of the Soviet Bloc. The agency was responsible for crushing the Hungarian Revolution in 1956 and the Prague Spring in 1968, among others.
In Latvia, the KGB had a wide network of informants reporting on Latvians that condemned Soviet power. Numerous political dissidents, artists, and writers were imprisoned or detained by the KGB, many in the Riga building.
Reuters photographer Ints Kalnins recently visited the newly re-opened headquarters and shared some of the photos here.
For many Latvians, the building is a symbol of totalitarian power. It has been vacant since 2008. 
The building is located in the downtown Centrs neighborhood of Riga, adjacent to the famous Old Town section of the city.
