The flag of Portugal consists of a rectangular (ratio 2:3) uneven vertical bicolor, that is, a fiel vertically divided into two unequal stripes of green, at the hoist, and red, at the fly. The minor version of the national coat of arms (armillary sphere and Portuguese shield) is centered over the boundary between the colors at equal distance from the upper and lower edges. Portugal officially adopted this design for its national flag on 30 June 1911, replacing the one used under the constitutional monarchy, after it was chosen among several proposals by a special commission, whose members included Columbano Bordalo Pinheiro, João Chagas, and Abel Botelho.
