לעיר אורבייטו שמרה על סודה: לבירינת של מערות ומנהרות שהיו קיימות מתחת לפני הקרקע . הם נחצבו באדמת הטוף הוולקנית, וכלפי המתבונן מבחוץ, הן לא היו ניתנים לגילוי. העיר התחתית נפתחה לסיורים מודרכים של תיירים. המימצאים הביאו לגילויים היסטוריים וארכאולוגיים.
מכלול העיר התחתית כולל, בנוסף למערות ומנהרות גם אולמות, בארות, מדרגות, מחצבות, גתותוכן מעברים סמויים בין חלקי העיר, מקוואות מים ומחבואים בכתלי הקירות.
בבתים רבים של המשפחות האצילות שגרו בעיר, נמצאו מסדרונות סמויים, אשר הובילו דרך העיר התחתית למקומות הרחוקים מהעיר. אלו שימשו אותם בעת מצור ומלחמה.
