The coat of arms was improved by Frederick III in 1462, in recognition of the service of king George of Poděbrady, by replacing the silver tincture by gold.

The full coat of arms in this period showed an imperial crown in the crest and two Bohemian lions as supporters.

[2] The Habsburg eagle in the crest was replaced by a third Bohemian lion in 1918, and the motto Praha matka měst ("Prague, the mother of cities") was added.

[1] It restored the crown of the Bohemian lion in the crest and changed the motto to PRAGA CAPUT REI PUBLICAE ("Prague, the Capital of the Republic").

State bodies and natural and legal persons may use the emblem and flag of the Capital City Prague only with the written consent of the Capital City Prague and the emblem and flag of a municipal district only with the written consent of the municipal district.
