It consists of a rectangular escutcheon (shield), featuring a part of the northern walls of Diocletian's Palace, as they appeared in the Medieval period.

The oldest confirmation of Split using the basic design of the rectangular coat of arms, featuring the north walls of the Palace, dates to the early 14th century.

The 1969 design essentially persists to this day, with the Yugoslav red star being replaced in 1991 (after the Breakup of Yugoslavia), with a white image of Saint Domnius on a blue background.

The arms used by the Split Hospital differ primarily in that the shield featuring a white Saint Domnius has a red background.

The city municipal transport company, Promet Split, uses a variant with a bus pictured exiting from the gates of the Palace.
