Plaza Colón is the main plaza in the city of Mayagüez, Puerto Rico. This plaza and its fountain commemorate the explorer Christopher Columbus, whose name in Spanish was Cristóbal Colón. The plaza presents the traditional urban relationship in Puerto Rico with the church, now Nuestra Señora de la Candelaria Cathedral on one end of the plaza and the "Alcaldia" or Mayagüez town hall in the other.
