Visiting Cusco, Peru, during Gay Pride month can be confusing and colorful for tourists. There are rainbow flags flying all over the city. This is because the city flag of Cusco, often mistakenly called the Inca flag, is a rainbow flag. The difference between the Cusco city flag from the LGBTI rainbow flag is an extra pale blue stripe. But, both flags are about freedom and pride. 
I saw many tourists getting very happy when they discovered that the pride flag of the city of Cusco was a rainbow.
