Skip the crowds at bigger cathedrals and head here for the 13th-century Gothic details that actually hold up. Spend about 45 minutes walking the perimeter and checking out the portal's ornate carvings. If you’re overwhelmed by the city's history, the 'I'll tell you Ascoli' guided experience is worth the $95 to actually understand what you're looking at. Go in the early morning for the best light on the stone facade. It's quiet, cool, and free.
