The chapel has a real bell, and it's yours to ring at any point during your window.
Most couples save it for the moment that deserves it: walking out of the chapel together, just married. Grab the rope together, ring it loud, and let the Hill Country know. It's a two-second tradition that turns into everyone's favorite photo.
A tip for the photo: let your photographer and videographer know the bell is coming so they're planted and ready — it happens fast, and the best shot is your guests' faces mid-cheer.
