Every Vampire universe has its own unique world-building elements, but one thing that every vampire fan wants to know is where was Dark Shadows filmed? The series was an American soap opera that aired for five days a week in 1966 and spawned a cult following that still thrives today.
The show's creators, Baran bo Odar and Jantje Friese, wanted a small town that wasn't just a generic German location; they wanted it to look like it could be anywhere in the world, with different time periods and parallel universes. That's why they looked around the city of Berlin, extending their search to Saarmund and Brandenburg.
They filmed the high school exteriors at Reinfelder Schule in Westend, and used a castle hotel near Brandenburg that was built in 1899 to owe its name to the actress Regina Tiedemann. They also filmed the bus stop with the traffic lights in the middle of a forest on the grounds of a driving academy in Zossen (TFR Fahrtechnik Akademie Kallinchen).
Filming the scenes for the Winden Caves where Claudia and Helge's journey into the past begins was done in a forest between Tremsdorf and Saarmund near Wildenbruch in south Berlin. This was a big job since the rocks and entrance set were completely fake, according to Fotostrasse who tracked the place down for us.
They also filmed at Pinewood Studios in Buckinghamshire, England for the Collinwood Manor and other interior shots. This is a studio that's been in use for decades, and it's the same facility where many films such as The Dark Knight and Jurassic World: Dominion were filmed. They also shot at the Isle of Mull in Scotland.
