Portugal Flag: Meaning, History, Colors & Pictures

Portugal’s national flag has unequal vertical fields of green and red, with green beside the flagpole. A white-edged national shield rests on a yellow armillary sphere at the color division. The flag’s height:length ratio is 2:3; green occupies two-fifths of its length and red the remaining three-fifths.

The main fields are dark green and scarlet red. The central emblem adds yellow, blue, white, and dark outlines. This page retains the palette of the Presidency’s downloadable SVG, including green #006035 and field red #ED1C24. These digital file values should not be mistaken for HEX specifications enacted in 1911.

Portugal’s national flag has a height:length ratio of 2:3. Its length is therefore one and a half times its height. A rectangle measuring 1,200 pixels wide by 800 pixels high has the correct shape. The ratio describes the flag itself, excluding a pole, sleeve, frame, or surrounding page margin.

The green field occupies two-fifths of the flag’s total length, while the red field occupies three-fifths. That is a 40% to 60% division, not equal halves. On the 2,400-unit drawing, the boundary is 960 units from the hoist, leaving 1,440 units for the red field.

Green is commonly associated with hope, but its selection also belonged to the republican political history of the flag. The commission connected green and red with revolutionary events. Reading green only as an abstract color of hope leaves out the circumstances in which the new national design was chosen.

Red is associated with vigor, struggle, blood, and sacrifice in explanations of Portugal’s flag. The commission’s language emphasized a forceful, enthusiastic color linked with victory. The familiar account of blood shed for the country is therefore part of a broader symbolic explanation, rather than a complete account of the design decision.

The emblem consists of Portugal’s white-edged national shield placed over a yellow armillary sphere with dark outlines. The shield contains five blue escutcheons and a red border bearing seven yellow castles. It sits at the boundary between green and red, which is left of the complete flag’s geometric midpoint.

The yellow armillary sphere recalls Portugal’s maritime history and its association with King Manuel I. The commission retained this older emblem within the republican flag. Its interlocking rings surround the national shield, connecting the new green-and-red field with an established historical symbol rather than introducing an entirely new set of arms.

The five blue shapes are small heraldic shields, or escutcheons, commonly called quinas in Portuguese discussions of the arms. They form a cross: one above, three across the middle, and one below. Each contains five white roundels. Their arrangement and contents are part of the flag’s recognizable national shield.

There are 25 white roundels inside the five blue shields: five roundels in each shield. Their arrangement places four around a central mark. Portuguese accounts call them besants. Traditional religious explanations sometimes introduce other numbers, but those interpretations do not alter the actual count visible in the present flag artwork.

Seven gold-colored castles appear on the red border of the national shield. Traditional explanations connect them with territorial development and the Algarve, while the commission associated the inherited arms with independence and national integrity. The present design contains seven castles; a precise list of seven conquered fortresses is not established here.

White appears around the national shield, within its central field, and in the roundels inside the five blue escutcheons. The white edging of the shield is expressly included in the 1911 design description. Although green and red dominate the rectangle, white is therefore an essential part of the complete national flag.

The complete central emblem is centered on the green-red dividing line and midway between the flag’s upper and lower edges. The 1911 construction text makes its height half the flag’s height. On this 2,400 × 1,600 master, its center is (960, 800), and its complete height is 800 units.

The present flag developed after the republican revolution of October 5, 1910. A commission prepared a new design, approved by the Provisional Government on November 29. The Constituent Assembly ratified the flag on June 19, 1911, and its construction details were published on June 30. These dates describe different stages.

June 19, 1911 is the date of the Constituent Assembly decree adopting the national flag. The decree appeared in the Government Gazette on June 20. The Provisional Government had already approved the design on November 29, 1910. June 30, 1911 is the publication date for its detailed construction provisions.

The design emerged from a five-member commission rather than a single credited designer. Its members were Columbano Bordalo Pinheiro, Abel Botelho, João Chagas, Ladislau Pereira, and Afonso Palla. The commission was appointed in October 1910, and the Provisional Government approved the final green-and-red design on November 29 of that year.

The Constitutional Monarchy used a blue-and-white national flag before the republican change. Green and red replaced those field colors after the 1910 revolution, while older elements of the national arms continued in the new composition. This guide describes that transition without presenting a modern speculative drawing as an authenticated historical flag.

The five kings and religious stories belong to traditional interpretations of the Portuguese arms. The Museum of the Presidency explicitly connects them with the legend of Ourique, formulated centuries after the supposed event. They should be identified as legends or later interpretations, while the present artwork’s five shields and 25 roundels remain directly countable.

Article 11 identifies the national flag as a symbol of the Republic’s sovereignty and Portugal’s independence, unity, and integrity. It refers to the flag adopted by the Republic instituted through the October 5, 1910 revolution. That constitutional reference establishes its national role; it is not a substitute for the detailed construction rules.

Portugal Day is celebrated on June 10 and is formally associated with Portugal, Camões, and Portuguese communities. It is distinct from the flag’s June 19, 1911 adoption date. The first republican flag festival took place on December 1, 1910. These observances and milestones should not be collapsed into one anniversary.

The ordinary national flag should be distinguished from specialized military and maritime patterns. The 1911 technical text separately describes unit flags with additional ornament and a jack with different construction. The general 1987 use law also preserves specialized rules. This package supplies the ordinary national flag, with those distinctions explained rather than reconstructed speculatively.

Green belongs at the hoist, the edge attached to the pole. In the usual front-facing reference image with the pole on the left, green therefore appears on the left. From behind the same cloth, the pole and green field appear on the right. The gallery labels that reverse view as a geometric reflection.

Decree-Law 150/87 requires the official pattern and good condition, and sets general rules for hoisting and respectful display. It specifies 9 a.m. to sunset, with illumination whenever possible if the flag remains up at night. Military, maritime, and certain international settings have particular provisions that must be considered in their own context.

During a declared period of national mourning, Portugal’s flag is placed at half-mast for the specified duration. Article 7 of the 1987 law requires raising it to the top before lowering it to the mourning position, and again before taking it down. Other flags displayed with it follow the lowered position.

The 1987 law gives Portugal’s flag the place of honor and provides arrangement-specific rules. With three masts it occupies the center; other layouts require attention to the law’s stated viewpoint and mast arrangement. International settings have specific protocol provisions. A universal instruction to put it on the viewer’s left would be incomplete.

Start with a 2:3 rectangle, divide its length into five equal parts, and color the first two green and the remaining three red. Place the complete shield-and-sphere emblem on that division, vertically centered, at half the flag’s height. Use verified vector artwork for the emblem rather than improvising its many small details.

Any dimensions with width:height 3:2 preserve the national flag’s shape. Examples include 600 × 400, 1,200 × 800, and 2,400 × 1,600 pixels. This package provides a 4,800 × 3,200 PNG and a vector SVG. Its labeled diagrams use separate canvas sizes so their explanations remain readable.

No. The SVG’s RGB values describe a particular official digital file, while print production involves different color systems, materials, and viewing conditions. The Presidency also supplies CMYK and Pantone artwork. A screen HEX table alone cannot certify dyed fabric or guarantee that a desktop print matches a physical national flag standard.

Frequent mistakes include equal green and red halves, a centered-in-the-rectangle emblem, an incorrect 2:3 shape, missing white edging, and simplified or miscounted heraldic details. Historical captions can also confuse the 1910 design approval with 1911 adoption. Check geometry, artwork, orientation, and date labels together rather than judging accuracy by color alone.

Choose the clean national-flag SVG for scalable vector artwork, or the 4,800 × 3,200 PNG for broad compatibility. The gallery also offers 23 explanatory subjects as SVG and PNG pairs. Those diagrams include labels and teaching layouts; they should not replace the unannotated flag when a complete national flag image is needed.
