Admiralteyskaya (Saint Petersburg Metro)

Opened on 28 December 2011, it is designed to relieve congestion at the Nevsky Prospekt and Gostiny Dvor stations, as well as to provide a more direct link to the Hermitage and other notable museums.

Thus, determining the location of the exit proved to be a difficult task that, after multiple attempts, was finally resolved on February 7, 2007.

With the issue seemingly resolved, the city officials began moving out the building's residents, completely emptying it by the end of 2008.

When the construction of what was originally intended as the northern branch of the Frunzensko-Primorskaya Line began, the underground vestibule of Admiralteystkaya was built, even as the location of the exit remained uncertain.

However, the lack of resolution over the status of the station's exit, combined with scarcity of funds, put further construction on halt.

When the northern branch was opened as a temporary part of the Pravoberezhnaya Line, the train passed the unfinished station without stopping, slowing down slightly while transversing it.
