Parroquia de San Miguel Arcangel anchors the main square and gives Bustamante its clearest piece of townscape. It is not a grand baroque showpiece like the famous churches of central Mexico; its charm is plainer, northern, and closely tied to the plaza life around it.
Step inside if the doors are open, then spend more time outside watching the square work. Benches, shade, small shops, and the church facade make this the easiest place to understand Bustamante as a living town rather than just a cave stop.
