As described by Article 21 of the Dominican Constitution, the flag features a centered white cross that extends to the edges and divides the flag into four rectangles; the top ones are blue (hoist side) and red, and the bottom ones are red (hoist side) and blue. The national coat of arms, featuring a shield with the flag design and supported by a bay laurel branch (left) and a palm frond (right), is at the center of the cross. Above the shield, a blue ribbon displays the national mottoDios, Patria, Libertad (English: God, Fatherland, Liberty). Below the shield, the words República Dominicana appear on a red ribbon (this red ribbon is depicted in more recent versions as having its tips pointing upward). In the center of the shield, flanked by three spears (two of them holding Dominican banners) on each side, is a Bible with a small cross above it and said to be opened to the Gospel of John, chapter 8, verse 32, which reads Y la verdad os hará libres (And the truth shall make you free).
The blue on the flag stands for liberty, the white for salvation, the red for the blood of heroes. The civil ensign follows the same design, but without the charge in the center. The flag was designed by Concepción Bona and Maria Trinidad Sanchez.
