It's a door, yes, but not any door. The Puerta de la Bandera is a place of national pride for all Puerto Ricans and a place of cultural appreciation for those who visit us. The door is painted with the Puerto Rican flag. The flag on the door was originally painted with the traditional colors of the Puerto Rico flag but in 2016, the year in which Puerto Rico lived tense economic and social situations, the flag was painted white and black as a symbol of protest and resistance. That caused the white and black flag to become a popular image that went viral on social networks.
