The document discusses the earthquake baroque churches built in Manila during the Spanish colonial period. It describes how the Spanish religious orders built many churches, monasteries and convents in Intramuros, transforming Manila into the "City of God". The churches were designed to withstand attacks during revolts, resembling fortresses. They blended religious and military purposes. Examples given include the Church of La Nuestra Señora de la Asuncion, which served as a citadel during crises, and the Church of Santo Tomas de Villanueva, which withstood attacks from Muslims. Architectural features of earthquake baroque churches included lower proportions, thicker walls, and lighter upper structures.
