In front of the Manila Cathedral is a small park with a fountain and a bronze statue. During the Spanish colonial period, the open space was called the Plaza Mayor and was the site of bull fights and other public events. In 1797, the Spanish Governor-General of the Philippines Rafael Maria de Aguilar y Ponce de Leon turned it into a garden. The bronze statue of Carlos IV, king of Spain from 1788 to 1808, was installed in 1824 as a tribute for his sending the first smallpox vaccine to the Philippines. During the American period, the park was named Plaza McKinley after William McKinley, who was then the president of the United States. Since 1960, it has been called Plaza Roma because of a reciprocal agreement between the Philippine government and the Vatican (there's supposed to be a Piazza Manila somewhere in Rome).
The Intramuros Administration says that they refurbished the park in 1980. I think it's about time that they reconditioned the bronze statue again.
