Throughout the years, the San Pedro Macati Church has undergone numerous renovations and design alterations, yet many of its original features, such as the reredos and the church bells, remain intact. Reflecting the Baroque style of architecture, the church structure comprises a single rectangular nave with an apse and sacristy, typical of churches from the Spanish Colonial Period. The altar, adorned with its original carved reredos featuring motifs of various flowers and fruits in the Baroque Rococo tradition, still graces the church.
