The new Revelin became the strongest of the city fortresses, safeguarding the eastern land approach to the city. Shaped in the form of an irregular quadrilateral with one of its sides descending towards the sea, it is protected by a deep ditch on the other. One bridge crosses the protective ditch and connects it to the Ploče Gate, while another bridge connects it to the eastern suburb. The construction work was executed so perfectly so that the devastating earthquake of 1667 did not damage Revelin. Divided into three large vaulted rooms in its interior, Revelin became the administrative center of the Republic.
