English: There is a fountain at each corner of the square, this is the Neptune fountain. There is also the Fountain of Prozerpingy, Fountain of Apollo and the Fountain of Mars. The square was originally laid out in 1253, with each side divided into 16 equal plots. Major changes were made from 1550 onwards. Most of the buildings in the square were reconstructed following heavy damage in the Battle of Poznan (1945).
