The mark consists of a design of a gray Latin cross with the letter D in the center. The cross is encased within a circular orange border that is in turn within a round decorative green border. The orange border has four, 3-pronged circular designs also within the border. The orange border also changes into a lighter shade of orange on the outside of the border. An inner circle that encloses the D in the center of the cross is green and the gaps within the cross are red. The design also features two tan colored banners at the top and bottom of the outermost green border that read, "The Seacoast" and "Irish Festival", respectively. The wording "Dover, NH" appears at the very bottom of the entire design with a stylized, coiled Irish serpent on either side. All wording is written with a black, Gaelic font in lower case format.
