Latest / The History of Portugal: The Small Nation That Built a Global Empire — Fexingo History / The Portuguese Crown Jewels Lost in the 1755 Earthquake
Transcript
- Luna: So we've talked about the Lisbon earthquake before, but I remember you said there was a whole story about the crown jewels that we never got into. Lucas: Right, episode 70 was mostly about the quake itself and Pombal's rebuilding. But the fate of the Royal Treasury — that's a wild piece of the story that deserves its own episode. On the morning of November 1, 1755, King José I and his family were at the Paço da Ribeira, the royal palace on the Tagus River. The king had actually gone to mass early that All Saints' Day with his family — a decision that probably saved their lives. Lucas: The tremors struck around 9:40 in the morning. The palace, which was one of the grandest in Europe, started swaying. Then the ceiling collapsed in some wings. But the real disaster came minutes later when the tsunami hit. A wall of water surged up the Tagus and smashed into the palace, dragging everything into the river. Luna: And the crown jewels were inside? Lucas: They were. The Treasury was kept in the Paço da Ribeira, in a specially guarded chamber. It held the royal regalia — crowns, scepters, the massive diamonds and emeralds from Brazil and India, gold plate, ceremonial swords. All of it went into the water. Some pieces were recovered later, but a huge portion simply vanished. The Braganza crown itself, with its famous diamonds, was lost for years. Luna: Wait — the crown itself? How does a crown just get lost? Lucas: Well, in the chaos after the earthquake, the palace was on fire. People were trying to salvage what they could. Some witnesses said that servants and guards managed to carry chests out into the courtyard, but then the tsunami swept them away. Later, divers searched the riverbed but found very little. The crown was reportedly found weeks later, half-buried in mud near the shore, but many of its gems were missing. Lucas: The loss was staggering. Portugal at the time was one of the wealthiest empires in the world, thanks to gold from Minas Gerais in Brazil and diamonds from the same region. The royal treasury was a symbol of that power. But within one morning, the entire physical representation of the monarchy's wealth was either destroyed or underwater. Luna: Did Pombal do anything about it? Lucas: Absolutely. The Marquis of Pombal, Sebastião José de Carvalho e Melo, was the king's chief minister. He had already shown incredible competence in organizing the relief effort. Within days, he ordered a systematic salvage operation. Divers were sent into the Tagus to retrieve whatever they could. But the river was deep, the current strong, and visibility zero. They managed to recover some gold bars, a few jewelry pieces, and some silverware, but the most valuable items — like the crown with its huge diamonds — were never found. Lucas: Pombal also used the disaster to centralize power. He stripped the church of some influence, reformed the treasury, and moved the royal court to a tent city in Ajuda, away from the river. The loss of the jewels became a kind of national trauma, a reminder that even empires can be humbled by nature. Luna: That's a really different angle on the earthquake — not just buildings but the very symbols of power. Lucas: Yeah, and it gets even more interesting when you think about what those jewels represented. The gold came from Brazil, which Portugal had claimed in 1500. The diamonds were from the same colony. Emeralds and other gems came through the Estado da Índia trade network. So the crown jewels were literally a map of the empire on the king's head. When they sank, it was like the empire itself was momentarily swallowed up. Lucas: There's also a fascinating detail about the 'lost jewels' of the Braganza dynasty. Some of those pieces were heirlooms dating back to the 17th century, when the Braganza family took the throne in 1640 after the Restoration War. They had been carefully preserved through wars and regencies. And in one morning, they were gone. Luna: I read somewhere that a few pieces eventually showed up in the 19th century — is that true? Lucas: Sort of. In the early 1800s, a large diamond that had been part of the royal collection was discovered in the possession of a Portuguese nobleman. It was claimed that he had recovered it from the river years after the earthquake. But by then, the kingdom was in turmoil, with the Napoleonic Wars and the royal family fleeing to Brazil. So the story gets murky. What's certain is that the royal regalia we see today in the Museu do Tesouro Real in Lisbon is almost entirely 19th-century or later — the pre-earthquake pieces are lost forever. Luna: It's wild to think that somewhere in the Tagus mud there are still diamonds and gold from the 1700s. Lucas: Exactly. And every now and then, people still speculate about treasure hunters finding them. But the river has been dredged, built over, and polluted for centuries. If anything survived, it's probably scattered across the bottom of the Atlantic by now. Lucas: The earthquake also changed how Portugal thought about its wealth. Before 1755, the crown displayed its riches openly in the palace treasury. Afterward, the idea of hoarding became less prominent. Pombal pushed for more practical investment — rebuilding Lisbon, strengthening the navy, consolidating the economy. The lost jewels became a symbol of the old world that had to be left behind. Luna: So in a way, the earthquake didn't just destroy the jewels — it ended an era of ostentatious display? Lucas: That's a really good way to put it. And you know, if today's conversation has been useful to you — and I hope it has — these episodes stay ad-free because of listener support.

Luna: Yeah, it's a small way to make sure we can keep diving into these corners of history without any ads interrupting. Lucas: Absolutely. So back to the story — one more thing I love about this: the earthquake actually gave us one of the first modern salvage operations in history. Pombal hired engineers and divers, some from Genoa, to try to recover the treasure. They used early diving bells and long poles with hooks. It was a technological effort that was remarkable for its time. Luna: Did they have any success at all? Lucas: Some. They recovered a significant amount of loose gold coins, bars, and some smaller jewelry. But the crown itself? Never. The best account we have says it was found by a common fisherman a few days after the quake, but he either sold it piecemeal or it was stolen and melted down. Either way, it's gone. Lucas: There's also a beautiful, tragic irony: the Paço da Ribeira was built during the Age of Discovery, when Portugal was at its peak. It housed the Casa da Índia, the royal monopoly on the spice trade. So the treasure in its vaults came from every corner of the world. And it all ended up in the Tagus. Luna: It really is a story about the fragility of empire. Lucas: Exactly. And that's what makes it so compelling — not just the lost gold, but what it meant for a nation to have its most cherished symbols wiped away in a single morning. The Portuguese never quite rebuilt the same kind of royal mystique after 1755. The monarchy became more practical, more bureaucratic, and eventually, in 1910, it was overthrown. Maybe the earthquake was the first crack in that old order. Luna: That's a really powerful way to think about it. Thanks for sharing this story, Lucas. Lucas: Thanks for listening. There's always more to uncover in history, and I'm glad we get to do it together.
