Oldest Stone Church
The Baclayon Church in Bohol is considered as the oldest stone church in the Philippines. But some historians disagree, claiming that San Agustin Church in Manila deserves the title.
Church historians claim that the cornerstones of San Agustin Church were laid as early as 1571, 25 years before Baclayon Church was built in 1596. But most people believe the title should be kept by the latter, since it is situated in the island first occupied by the troops of Miguel Lopez de Legazpi, the country's first Spanish governor general.
Bohol was where a friendship was sealed with blood between chieftain Rajah Sikatuna and Legazpi. The event is known today as ''The20Blood Compact.''

The University of Santo Tomas, however, contests this title. Formerly known as the Colegio de Nuestra Señora del Rosario, UST was the first school, which got a university status in 1645. USC became a university in 1948. UST also claimed that the original USC was closed in 1769 as a result of the expulsion of the Jesuits. It reopened in 1783 under a new name and ownership. But the USC officials stick to their claim. The university observed its 400th foundation day on August 21, 1995.
