Which area is noted as the first "university town" due to its centered churches?

The area noted as the first "university town" due to its centered churches is Sampaloc. This designation stems from the presence of numerous educational institutions and a rich historical context that highlights the coexistence of religious and educational establishments. Sampaloc is home to some of the oldest academic institutions in the Philippines, such as the University of the East and various colleges and universities that have emerged around the area.

Additionally, the presence of various churches in close proximity to these educational institutions emphasizes the role of faith and religion in the development of the community, establishing it as a prominent area dedicated to learning and spiritual growth. This unique combination of educational and religious elements encapsulates why Sampaloc is recognized as the first "university town."

In contrast, while the other areas such as San Miguel, Ermita, and Sta. Cruz may also have significant historical and cultural relevance, they do not similarly embody the specific characteristics that unite education and ecclesiastical presence in the same way that Sampaloc does.
