Poznań is the largest city from all locations you mentioned, and that's why I am talking about it.
I'll give you some translation from the wiki page I provided you above:
Piotrowo - part of Poznan, local government settlement Rataje, between Swiety Roch in the south and Berdychow on the north, by the street of the same name, near the Rondo Rataje. There is located the largest Campus of Poznan University of Technology [...]
Piotrowo was formerly a ducal village, and in 1253 (location on the left bank of Poznan) was given to the city, as the economic base. In 1602 Piotrowo received town rights and in 1896 was incorporated into Poznań.
In the period of 1954-1990 Piotrowo belonged to the Nowe Miasto area, and in the years 1996-2010 to the Rataje nad Warta settlement
