Caprican Bay was an area of water surrounded by and adjacent to Caprica City, Caprica. The Pantheon Bridge traversed Caprican Bay.
Fifty-eight years before the Fall of the Twelve Colonies, Doctor Amanda Graystone attempted suicide by jumping off the Pantheon Bridge into Caprican Bay. Unlike many past jumpers, Graystone survived her fall into the bay, though severely injured (CAP: "End of Line", "Unvanquished").
