The flag of Portugal
Bandeira de Portugal · since 1911
A green and red vertical bicolour, the green taking two fifths of the length, with the armillary sphere and the shield of Portugal set over the line between them. The green and red were the colours of the Republican Party, and the flag was chosen after the revolution of 5 October 1910 to break with the blue and white of the monarchy. The shield of five blue escutcheons and seven castles has been on every Portuguese flag since the Middle Ages except the first.

Construction
How the flag is drawn
A field divided vertically, dark green at the hoist over two fifths of the length and scarlet over the remaining three fifths, with the lesser national arms centred on the line between them: a yellow armillary sphere lined in black, and on it a red-bordered shield with seven yellow castles round a white field bearing five blue escutcheons in a cross, each with five white bezants.
- Field
- Green over 2/5 of the length at the hoist, red over the remaining 3/5
- Armillary sphere
- Diameter half the height of the flag, equidistant from the top and bottom edges, centred on the colour boundary
- Sphere
- Drawn in perspective with six arcs: the ecliptic, the equator and two meridians as great circles, and the two tropics as small circles
- Shield
- Height 7/10 and width 6/10 of the sphere's diameter, centred vertically on the sphere
- Bordure
- Seven castles: three in chief, one on each flank, and two turned 45° on the curved base
- Tropic of Capricorn
- A segment is left out between the shield and the ecliptic in the official drawing
Other forms

Meaning
What each part stands for
- Green and red
- Chosen as the colours of the republican flags of the 1891 revolt in Porto and of the revolution of 5 October 1910. The commission's report gave them no national meaning; the reading of green as hope and red as the blood of those who died for Portugal took hold under the Estado Novo
- Armillary sphere
- The emblem of Manuel I and of the voyages of discovery, which the commission revived as the standard of the adventurous spirit of the Portuguese
- Five blue escutcheons
- Popularly the five wounds of Christ and the five Moorish kings of the legend of Ourique, a legend first written down in the 14th century
- Seven castles
- Traditionally the conquest of the Algarve under Afonso III. More likely from his family ties with Castile, and the number was fixed only in 1578
Who drew it
- Columbano Bordalo Pinheiro
- Painter, author of the drawings of the flag, on the commission appointed on 15 October 1910
- João Chagas
- Journalist, member of the commission
- Abel Botelho
- Writer, member of the commission and author of its report of 29 October 1910
