King Felipe VI of Spain toured St. Augustine's centuries-old Spanish-built castle and other historic sites in his country's former colony before addressing hundreds of well-wishers from a balcony downtown.

The king on Friday toured the oldest city in the U.S. with his wife, Letizia, to celebrate St. Augustine's 450th anniversary and attend a meeting of the U.S.-Spain Council.

The royal couple was in Miami on Thursday, where Felipe gave a speech at Miami Dade College. He also met with President Barack Obama on this trip, where the two discussed refugees.

The 47-year-old became king last year, replacing his scandal-hit father, former King Juan Carlos, who abdicated the throne.

Chanting "Viva Espana,' or long live Spain, hundreds including school kids gathered in St. Augustine's Plaza de la Constitucion to catch a glimpse of Spain's glamorous royals.
