the Saltykov Mansions. Military parade ground In 1799 an obelisk designed by Vincenzo Brenna was installed in the centre of the field in honour of Pyotr Rumyantsev, and in 1801 Mikhail Kozlovsky's Suvorov Monument was unveiled on the south side of the field. During the brief reign of Paul I, the Tsaritsyn Meadow was used mainly for military parades and drill, with his son, Alexander I transferring the land from the city authorities to the military. On 16 May 1803 carousels, booths and other amusement pavilions were erected on the land as part of the celebrations of the centenary of the founding of Saint Petersburg. The martial nature of the area was reinforced with the renaming of the Tsaritsyn Meadow as the "Field of Mars" in 1805, commemorating Mars, the God of war in Roman mythology, whom Kozlovsky had depicted Alexander Suvorov as on his monument. The new name also referenced the Campus Martius in Rome and the Champ de Mars in Paris, drawing parallels and asserting that Saint Petersburg was also to be considered as a great European capital. The name "Tsaritsyn Meadow" however continued to appear on some maps up until 1917. Pushkin acknowledged the military connection in his 1833 poem The Bronze Horseman; I love the military vigourParaded on the Field of Mars:Stout-hearted foot troops and hussarsIn orderly and pleasing figure;Torn battle colours held on high;Smart ranks in measured rhythm swaying;Glint of brass helmets, all displayingProud bullet scars from wars gone by. Military use trampled the remaining grassy surface to dust, which when raised by the soldiers' boots, blew across the city, often settling in the trees of the nearby Summer Garden, and earning the Field of Mars its nickname of the "Saint Petersburg Sahara". 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
