Sennaya Ploshchad (Russian: Сеннáя плóщадь, Sennaya Square) is a station on the Moskovsko-Petrogradskaya Line of Saint Petersburg Metro, opened on July 1, 1963. It is a deep underground pylon station. Its surface vestibule is situated near Sennaya Square, which gives its name to the station. Construction of the entrance to the station was given as a pretext for demolition of the Saviour Church on Sennaya Square. Before 1992 both the square and the station were known under the name Ploshchad Mira (Peace Square). In June 1999 the concrete canopy of the surface vestibule collapsed, killing seven. The station is connected to the station Spasskaya of the Pravoberezhnaya Line and Sadovaya of the Frunzensko-Primorskaya Line via an underground transfer corridor.
