Parroquia Santiago Apostol is one of the 16th-century mission churches of Morelos, with the mix of fortress-like walls, open chapel and courtyard that marked early colonial religious architecture in central Mexico. The artwork is the detail to look for, especially where Indigenous motifs and Christian imagery sit side by side.
It is a worthwhile stop if you are using Cuautla as a base for the region's convents, churches and revolutionary history.
