The Corner House — Uncover Soviet Latvia's Darkest Secret

🎭Your Mission

You are a Latvian KGB archivist tasked with a secret mission in occupied Riga in 1975.

You must trace a resistance network operating from the Stūra māja, that mysterious

Uncover the mysteries of Soviet surveillance in Riga, where every medieval facade hides 50 years of police terror and clandestine resistance.

The story that haunts this land

Riga awakens in terror on June 17, 1940, when the Red Army crosses the Daugava. The Monument of Freedom, inaugurated in 1935 by Kārlis Zāle to celebrate 1918 independence, disappears behind barbed wire. Its golden 42.7-meter statue, Mother Latvia, becomes the forbidden symbol of an erased nation. During 51 years of occupation, laying flowers at the monument's base constitutes an act of resistance punishable by deportation to Siberia. You begin your investigation on this square where every gesture was watched.

The Orthodox Cathedral of the Nativity of Christ reveals the first phase of forced Russification. Completed in 1883 under the Tsarist Empire, its 5 golden domes rising 48 meters dominate Riga to assert Orthodoxy against Baltic Protestantism. But in 1950, the Soviet regime pushes irony further: it transforms this church into a museum of atheism, confiscates its bells and displays anti-religious propaganda. Latvians discover that their successive oppressors use the same methods of ideological control.

At the heart of your investigation stands the Stūra māja, this Corner House from 1685 that became a dark legend of occupation. Only 2.23 meters wide, it allegedly served as a privileged observation post for the NKVD then KGB, monitoring comings and goings between Kalķu iela and Maza Pils iela. Although this use is debated by historians, Latvians still whisper that its narrow windows hid agents who filed every Old Town resident. Restored in 1996, it keeps its secrets.

Riga Castle perfectly illustrates the continuity of oppression. Founded in 1209, residence of Russian governors in the 19th century, it becomes under Stalin the seat of the October Revolution Museum, temple of Soviet propaganda until 1991. The Three Brothers, 15th-century residential ensemble at 17-21 Maza Pils iela, suffer the humiliation of overcrowded collective housing: these architectural jewels classified UNESCO in 1997 housed entire families in a single room, symbol of planned urban degradation.

Your journey through Riga reveals a chilling truth: the most refined medieval architecture can mask the most sophisticated control systems. From Saint Peter's Cathedral, whose 123.6-meter bell tower was rebuilt in 1973 under close surveillance, to the House of Blackheads, destroyed in 1941 and rebuilt in 2001 as a symbol of national resurrection, every stone of this UNESCO city carries the memory of 50 years of silent resistance. You leave with the disturbing certainty that the darkest history often hides behind the most beautiful facades.
