Where they filmed the TV series Northern lights, where the shooting took place?

Very interesting series or TV series, consisting of several two-part episodes "the Northern lights" on the works of women writers Victoria plateway, which I really like. While out on the first two films, and the action in both takes place on the same mysterious island. Filming also took place in several places of St. Petersburg and the Leningrad region in Sosnovy Bor, in Kronstadt, on Krestovsky island. In the series, good story and great actors, including a small but very well-known Vitaly Kornienko. The main character is a writer in the detective genre Agatha North, played by actress Irina Goryacheva.
