Step away from the bustling main squares and find a moment of peace in the Chiesa di Sant'Agostino. While its exterior is a simple, austere brick, the inside holds a treasure trove of Renaissance art. You'll be captivated by the famous fresco cycle by Benozzo Gozzoli depicting the life of St. Augustine, a vibrant masterpiece tucked away behind the main altar. It's a wonderfully quiet spot to reflect and admire some of the town's finest art without the crowds.
