The station opened on 1 July 1963. It is a deep underground
pylon station. Its surface vestibule is situated near
Sennaya Square, which gives its name to the station. The historic
Saviour Church on Sennaya Square was demolished in 1961 prior to the construction of the vestibule, although it ended up located in a different place. In 1952, Sennaya Square was renamed
Ploshchad Mira and the new station was given that name. The historic name of the square was restored in 1992, and the metro station was also renamed. 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. On 3 April 2017, a
suicide bomber blew himself up on a train between stations Sennaya Ploschad and
Tekhnologichesky Institut, leaving 15 people dead and at least 45 people injured. ==References==
