Luanda is the capital of Angola. Brazil and Angola, being two parts of Lusophony with shared history, developed a close friendship. Luanda, for example, is friend city of my hometown, São Paulo.
As far as I know, Luanda doesn't have a flag. It acquired a coat of arms while still part of Portuguese Angola, but I couldn't check if it's still used:
This flag showed Our Lady of the Assumption in a blue field, and St. Paul in a red field. Those were the patron saints of Luanda, and its full name was "St. Paul of Assumption of Luanda".
Inspired by the coat of arms, I designed the following flag:
The symbol in the middle of the flag is a stylized cowry, formerly used as currency in many parts of Africa and the world. It represents the shell money extracted in the island of Luanda, but also the wealth of the city and its African roots; it's also related to one of probable origins of city's name.
Comments are welcome.
I have exciting news for next week. Wait!
