This pin is showing the ship wich stands on top of the Admiralty building in St. petersburg.
The Admiralty is the former headquarters of the Admiralty Board and the Imperial Russian Navy in St. Petersburg, Russia and the current headquarters of the Russian Navy. The edifice was rebuilt in the nineteenth century to support the Tsar’s maritime ambitions. Located at the western end of the Nevsky Prospekt, The Admiralty with its gilded spire topped by a golden weather-vane in the shape of a small sail warship (Korablik), is one of the city’s most conspicuous landmarks and the focal point of old St. Petersburg’s three main streets underscoring the importance Peter I placed on Russia’s Navy.
