Today is the day Puerto Rico marks as the day Europeans "discovered" their island. Puerto Rico's national anthem, called La Borinqueña, fancifully describes this discover in these words:
Cuando a sus playas llegó Colón exclamó lleno de admiración, Esta es la linda tierra que busco yo, es Borinquen, la hija, la hija del mar y el sol
Translation:
When he arrived on her beaches, Columbus exclaimed, full of admiration, This is the beautiful land that I seek, it is Borinquen, the daughter of the sea and the sun.
