Thecoat of arms ofPoznań consists of white (not silver) city walls with three towers. On the left (heraldic) tower standsSaint Peter with a key and on the heraldic right one standsSaint Paul with a sword. In the gate there are two golden crossed keys with a cross above. Over the middle tower, which contains a single window and is topped by abattlement, there is agothic shield with a white eagle in crown. On the sides of the two saints there aregolden crescents and stars. All of those elements are on a blue field. Over the shield there is golden crown. Author of modern version of coat of arms is Jerzy Bąk.
The first known image of the Poznań coat of arms is on the seal of a document dated 1 May1344. It contains all of the elements of the modern coat of arms except the crown over the shield. Throughout history, simpler versions were sometimes used: with only walls and keys or even only keys and cross on blue field. In 1440 kingVladislaus III of Varna gave Poznań the right and privilege to seal documents with red, royal wax. This privilege also allowed the town court to judge people of all estates, including nobles and church hierarchs.
DuringPrussian-German rule, thePolish white eagle on a red background was coloured black on a gold background (aPrussian eagle), and the city towers were brick-red instead of white.
