The next major redevelopment of the area was in 1818, with architect Carlo Rossi including it in the development of his architectural ensemble to the south, centred around the Mikhailovsky Palace estate. The Rumyantsev Obelisk was removed to Vasilyevsky Island while the monument to Suvorov was relocated to a new square, later named Suvorov Square, north of the Field of Mars on the Neva embankment, and between the Marble Palace and the Saltykov Mansion. Between 1817 and 1821 a large building alongside the west of the square was built to the design of Vasily Stasov to house the , with the western ensemble completed with houses between the Moyka and the south of the Pavlovsky Regiment building. In 1823, as part of the redevelopment of the land around the Field of Mars and the Mikhailovsky Palace, Sadovaya Street was extended up to the eastern edge of the Field of Mars, joining the pathway running parallel to the Swan Canal, and connecting with Millionaya Street which crossed the northern boundary.
