The door is thick. It doesn’t have a latch, a keyhole, or even a visible seam where it might swing open. Instead, two massive cobras are carved into the stone, frozen in a warning that has lasted for centuries. This is Vault B Padmanabhaswamy Temple, a place that has basically become the world's most expensive "Do Not Disturb" sign.
You’ve probably heard the rumors. People talk about the "Nagabandham" or the snake bind—a legendary spell that supposedly seals the door. Skeptics call it a clever piece of ancient engineering designed to scare off looters. But when you’re standing in the humid air of Thiruvananthapuram, looking at a temple that holds enough gold to crash a small country's economy, the myths start to feel a lot more like warnings.
It’s not just about the money. Sure, the other vaults—A, C, D, E, and F—contained a mind-blowing stash of gold coins, 18-foot diamond necklaces, and solid gold idols. We’re talking about an estimated $20 billion in treasure, making the Sree Padmanabhaswamy Temple the richest place of worship in recorded history. But Vault B is different. It’s the one they didn't open. The one the Supreme Court of India stepped back from. The one the royal family of Travancore says will bring a literal apocalypse if the seal is broken.
The Secret History of the "Bharatakkon"
Most people think Vault B is just one room. It’s actually more like a series of chambers. There’s the Kallara (cellar) which is divided into the Mahabharatakkon and the Sreechakram. According to the temple's records and the testimony of the royal family, the inner-most chamber is where the real mystery lies.
This isn't some Indiana Jones movie set. It’s a functional part of a living temple. The Travancore Royal Family has been the "Padmanabha Dasa" (servants of the Lord) for generations. To them, the treasure isn't wealth; it's the deva prasnam, the property of the deity. They argue that opening Vault B Padmanabhaswamy Temple would be a spiritual violation.
Back in 2011, when the inventory started, the world watched as Vault A gave up its secrets. It was like a floodgate of history. Roman gold coins from the time of Augustus. Napoleonic era currency. Bags of rubies the size of pigeon eggs. But when the committee reached the iron door of Vault B, things got weird.
The story goes that the observers tried to open it, but the lock was stuck. Or maybe there was no lock. Reports from that day are strangely vague. Some say they heard the sound of rushing water behind the door. Others mention a sudden feeling of dread. What we know for a fact is that the Supreme Court-appointed committee stopped. They didn't push it.
Why the Curse Might Be Real (Sorta)
Is there a curse? Honestly, it depends on who you ask.
T.P. Sundararajan, the man whose petition originally led to the opening of the vaults, died shortly after the inventory began. People immediately pointed fingers at the "wrath of the deity." Then there were reports of family members of temple officials falling ill. It’s easy to dismiss this as coincidence—Sundararajan was elderly and already in poor health—but in the local culture, these events carry heavy weight.
There's also the physical danger. Many believe the vault is connected to the Arabian Sea. The "sound of water" heard by the committee might actually be an ancient hydraulic security system. If you force the door, you don't just get the gold; you flood the entire temple complex. It’s a brilliant, low-tech fail-safe that has kept the Vault B Padmanabhaswamy Temple intact for hundreds of years.
The Legal Tug-of-War
The Indian government and the Supreme Court are in a tough spot. On one hand, you have a massive amount of wealth that technically belongs to a public trust. On the other, you have deep-seated religious beliefs and the rights of the royal family.
The court has gone back and forth. For a while, there was a push to digitize everything and move the gold to a museum. But the backlash was intense. In 2020, the Supreme Court of India upheld the right of the Travancore Royal Family to manage the temple. This was a huge win for traditionalists. It also effectively put a "wait and see" tag on Vault B.
- Vault A: Opened. Contained the bulk of the $20 billion treasure.
- Vault B: Unopened. Sealed with the "Nagabandham."
- Vaults C through F: Opened. Contained ritual items and some gold, regularly used for festivals.
- Vaults G and H: Discovered later, mostly containing copper and silver.
The complexity here is staggering. How do you audit a God? If the gold belongs to Lord Padmanabha, then the state has no right to it. But the state has a duty to protect it from theft. The temple is now one of the most guarded buildings in India, with machine-gun nests, metal detectors, and 24/7 surveillance.

The Mystery of the Inner Door
Inside Vault B, there are actually three doors. The first is a metal grille. The second is a heavy wooden door. The third is the famous iron door with the cobras.
The royal family claims that this third door can only be opened by a "Siddha Purusha" or a high-level monk who knows the "Naga Mantra." Since there aren't many of those hanging around Thiruvananthapuram these days, the door stays shut.
Interestingly, there are records from the 1930s suggesting that an attempt was made to open the vault during a time of famine. According to the book Travancore: A Guide Book for the Visitor (1933) by Emily Gilchriest Hatch, the explorers found a place infested with cobras and fled for their lives. Again, was it real snakes or just a very effective psychological barrier? We don't know.
The Wealth Beyond Gold
We focus on the gold because, well, it’s gold. But the historical value of Vault B Padmanabhaswamy Temple is arguably higher. The items found in the other vaults show that Kerala was a massive hub for global trade centuries ago. The presence of Roman, Venetian, and Dutch coins proves that this temple was a central bank for the spice trade.
Opening Vault B could rewrite history books. It could show us even older connections to the Silk Road or the Roman Empire. But at what cost?
The debate isn't just about greed vs. religion. It’s about the preservation of mystery in a world where everything is scanned, tagged, and uploaded. There is something deeply human about leaving one door closed.
What Happens Next?
Don't expect the door to swing open tomorrow. The legal status of the treasure is "protected but untouchable." The current administration of the temple is focused on security and the massive logistics of managing the millions of devotees who visit.
If you’re planning to visit, remember that the temple has a strict dress code. Men must wear a dhoti (mundu) and remain bare-chested. Women must wear a saree or a long skirt. You won't get anywhere near the vaults, but you can feel the weight of the place. The air is thick with incense and the sound of chanting. Even without seeing the gold, you can feel the "power" that people talk about.
Actionable Insights for the Curious
If you are fascinated by the mystery of the temple, here is how you can actually engage with it without breaking any laws or curses:
1. Study the Travancore Royal Records
The history of the temple is meticulously documented in the Mathilakam records. While most are in ancient Malayalam or Tamil, scholars like Dr. M.G. Sasibhooshan have written extensively on the cultural impact of the temple's wealth.
2. Visit the Napier Museum
Located in Thiruvananthapuram, this museum holds many artifacts related to the Travancore royalty. It gives you a sense of the aesthetic and scale of the craftsmanship that produced the temple's treasures.
3. Respect the Devaswom Board Guidelines
If you visit the temple, follow the rules. It is a place of worship first and a mystery second. Photography is strictly prohibited inside the complex, and for good reason.
4. Follow the Supreme Court Bulletins
The case isn't "closed." Periodically, the court reviews the security and the audit reports. Any news about Vault B will come from an official court mandate, not a leaked video or a "discovery" show.
The gold is staying put. The snakes are still on the door. For now, the Vault B Padmanabhaswamy Temple remains the world's greatest unfinished story. And maybe that's exactly how it should stay.
Next Steps for Your Research:
- Examine the 2014 Amicus Curiae report by Gopal Subramanium, which detailed some of the mismanagement that led to the initial inventory.
- Compare the Padmanabhaswamy Temple architecture with the Adikesava Perumal Temple in Kanyakumari; they are "twin" temples with very similar layouts.
- Look into the sovereign rights of the Travancore family versus the Indian Constitution, which is the core of the ongoing legal debate.
