The sunken palace
The sunken palace, known in Turkish as Yerebatan Sarayi, is the ancient Byzantine cistern beneath Istanbul that serves as the novel's climactic setting. Built in the sixth century to house the city's water supply, this vast subterranean chamber is supported by 336 marble columns and contains a shallow lagoon of water. It is here that Bertrand Zobrist, the novel's antagonist, concealed his genetically engineered plague, Inferno, in a dissolving Solublon bag, making the cistern the focal point of the final confrontation between the protagonists and the forces seeking to either release or contain the pathogen.
Description and History
The sunken palace is a cathedral-size subterranean room, nearly two football fields in length, with a ceiling spanning more than a hundred thousand square feet. Its floor is a glassy sheet of dark, still water, described as "the lagoon that reflects no stars." The cistern was originally built to store the city's water supply, but after modernization, it fell out of use and became a tourist attraction, complete with boardwalks over the water and even a small café. The cavern is lit by red spotlights, creating a surreal, hellish atmosphere that mirrors Dante's vision of the underworld. The air is humid and stuffy, with limited ventilation, making it an ideal environment for an airborne pathogen to incubate.
Zobrist's Plan and the Plague
Zobrist chose the sunken palace as the release point for his sterility plague, Inferno, because of its symbolic and practical significance. The cistern's name, Yerebatan Sarayi, literally means "sunken palace," a phrase that appears in the poem on the back of Dante's death mask, guiding the protagonists to this location. Zobrist tethered a Solublon bag containing the virus to the floor of the lagoon, where it would dissolve over time, releasing the pathogen into the water. The virus then aerosolized, infecting the thousands of tourists who visited the cistern daily, including those attending a week-long concert series of Liszt's Dante Symphony, which Zobrist had anonymously underwritten. The date on the plaque bolted to the cistern floor—tomorrow—was not the release date but a mathematical projection of when the virus would have saturated the global population.
The Climactic Confrontation
The novel's climax unfolds in the sunken palace as Robert Langdon, Elizabeth Sinskey, and Agent Brüder race to contain the plague. They discover that the Solublon bag has already dissolved, and the virus has been released for a week. The cistern is teeming with the pathogen, and the entire area is in a state of panic. Sienna Brooks, who has been pursuing her own agenda, reveals the true nature of the virus—a sterility plague that will render one-third of the human population infertile—and agrees to cooperate with the World Health Organization. The stampede of concertgoers fleeing the cistern creates chaos, and Langdon chases Sienna through the streets of Istanbul, culminating in a confrontation at the docks where she finally surrenders and agrees to help.
Symbolic and Thematic Significance
The sunken palace is a powerful symbol of the novel's central themes: the hidden dangers of unchecked population growth, the intersection of art and science, and the moral complexities of genetic engineering. The cistern's subterranean, water-filled space evokes Dante's vision of hell, particularly the river Cocytus and the lagoon that reflects no stars. The inverted head of Medusa, a chthonic monster, serves as a guide to the location of the plague, linking Zobrist's creation to the fertility myths of the ancient world. The cistern's transformation from a functional water supply to a tourist attraction and finally to a site of biological catastrophe mirrors the novel's critique of humanity's denial of the overpopulation crisis. The sunken palace is not just a setting but a character in its own right, embodying the hidden, subterranean threat that Zobrist has unleashed upon the world.
