Admiralteyskaya is a station on the Frunzensko-Primorskaya Line of the 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. However, the completion of the station was hampered by the lack of funds and ongoing controversy over the placement of the station's exit. The station will eventually provide a transfer to the Nevsko-Vasileostrovskaya Line station tentatively designated Admiralteyskaya-2. After the exit location was settled, the station Admiralteyskaya-1 on the Frunzensko-Primorskaya Line was scheduled to open in 2008, but concerns over the station's historic significance pushed the opening back. In June 2009, the issue was finally settled and the station opened on 28 December 2011.

Line 5 of the Saint Petersburg Metro, also known as Frunzensko-Primorskaya Line or Purple Line, is a newest rapid transit line in Saint Petersburg, Russia, opened in 2008, which connects the historical city centre to the northwestern and southern districts. It has 15 stations covering a total length of 26.2 kilometres (16.3 mi). Although it opened on 20 December 2008, parts of the line are considerably older. At its official opening in 2008, it included only two stations that opened concurrently with the line. On 7 March 2009, the Metro incorporated six existing stations of Line 4 (Pravoberezhnaya) into Line 5, expanding it to nine stations.
