Vilnius KGB HQ
In central Vilnius, the Soviet KGB had its headquarters and prison. The headquarters is located next to a park that during Soviet times was called Lenin Square and was adorned with a magnificent statue of Lenin (the statue now stands in Grutas park). After the Soviet Union reoccupied Lithuania in 1944, the square was used by the Soviet Security Service NKVD for public executions of Lithuanians. When the Soviet Union collapsed, the KGB destroyed all secret material, but otherwise left the building intact.

Something that is interesting about the museum is that much of the original interior is preserved, which makes everything more authentic. The museum is modern and closer than this, you probably won’t come to the depiction KGB.
