Old flag of portugal
Portugal has used several historical flags. Before the current green-and-red design was adopted in 1911, the national flag was predominantly blue and white, with the royal coat of arms.
Location and boundaries
The earlier design reflected the monarchy. The current flag’s colors and emblem were introduced after the 1910 revolution and establishment of the republic.
Geographic context
Portugal’s blue-and-white flag belonged to the monarchy, while the current green-and-red flag followed the republic’s establishment. Historical flags changed as dynasties and political institutions changed. A timeline should label each design by period rather than call one design the only “old flag.”

Using this location information
Portugal’s republican flag has green on the hoist side and red across the larger field, with the armillary sphere and shield near the boundary. The previous blue-and-white flag used royal symbols. “Old Portuguese flag” can refer to more than one historical design, so dates matter.
