Vilnius served as the primary filming base, with 57 days of shooting scheduled in the city. The production filmed in the districts of Naujamiestis – the New Town, with its mix of 19th-century and Soviet-era architecture – and Lazdynai, the planned residential district built in the late 1960s, whose uniform apartment blocks and wide concrete spaces provided the look of an East German housing estate.
“Vilnius is a very modern city, and sometimes it can be challenging to hide contemporary details,” Hall explained on the Vilnius Film Office site. “However, we found some remarkable locations here.”
“I think it was one of the coldest winters in fifteen years or something,” said Ann Skelly. “So it was just like thick, thick snow.” For a series set behind the Iron Curtain in midwinter, the weather did the production’s work for free.
The standout Vilnius location was the Palace of Culture, Entertainment and Sports – a former cultural building associated with the Ministry of Internal Affairs. Its imposing interiors were transformed into several different on-screen environments: a bridal salon, secret police offices, interrogation rooms and corridors.
