The church of San Miguel's spiral pillars, carved wooden altar with a flying San Miguel, extravagant golden pulpit, religious artwork, toy-like bell tower and elaborately painted facade are simply superb. Although not designed by Martin Schmidt, the church does reflect his influence and is often considered the most beautiful of Bolivia’s Jesuit missions.

　　A unique feature of San Miguel is the presence of no fewer than seven bells in the bell tower. When rung in combination they transmit a complicated code language to the populace. The largest bell rung in tandem with two others signals the departure of a dignitary, rung alone it’s the baptism of a child, while a special bell calls the faithful to prayer.
