When you think about the power players in Westeros, your mind probably goes straight to the lions of Casterly Rock or the wolves in the North. It’s natural. We spent eight seasons watching the Starks and Lannisters rip the realm apart. But if you really dig into the history of George R.R. Martin’s world, you realize that House Hightower has been pulling the strings from the shadows for thousands of years. They aren't just some secondary noble house from the Reach. They are the oldest, wealthiest, and arguably the most sophisticated dynasty in the Seven Kingdoms.
They stayed out of the spotlight for a reason.
While the Targaryens were busy burning things down with dragons, the Hightowers were busy building the foundations of civilization. They live in the Hightower—the massive lighthouse-fortress in Oldtown that is actually taller than the Wall. Think about that. While the Night’s Watch is freezing on a pile of ice, the Hightowers are sitting in a literal skyscraper, watching the sunset over the Sunset Sea. They don't need to shout "Hear Me Roar" because everyone already knows who holds the purse strings and the books.
The Oldest Blood in Westeros
Most fans don't realize that House Hightower predates almost everyone. They were kings before the Andals arrived. They were kings when the First Men were still figuring out how to farm. According to The World of Ice & Fire, the foundations of the Hightower on Battle Island are made of a strange, fused black stone that some Maesters think resembles the work of the Valyrians, even though it was there long before Valyria was even a city.
It’s eerie.
Some theories suggest it might even be linked to the Deep Ones or some other Lovecraftian horror, but the Hightowers don't care about rumors. They just built a city around it. Oldtown is the crown jewel of the Reach. It’s the center of the Faith of the Seven and the home of the Citadel. If knowledge is power, the Hightowers own the factory. They didn't fight Aegon the Conqueror with swords; they were smarter than that. When Aegon showed up with Balerion the Black Dread, the High Septon locked himself in the Starry Sept for seven days. He came out and told Lord Manfred Hightower that the city must open its gates.

Result? Oldtown wasn't burned. The Hightowers kept their heads, their gold, and their titles.
Wealth That Rivals the Lannisters
Everyone talks about Lannister gold, but the Hightowers are "rich as a Lannister" in a much more stable way. They don't rely on mines that can run dry. Their wealth comes from trade. Oldtown is the busiest port in the world. Every ship coming from the Summer Isles, Volantis, or Braavos stops there.
They tax the trade. They own the docks.
Honestly, while the Tyrells are technically the "Liege Lords" of the Reach, everyone knows the Hightowers are the real heavyweights. In the books, Lord Leyton Hightower hasn't left the top of his tower in over a decade. He’s supposedly up there with his daughter, the Mad Maid, consulting spellbooks and gazing at the stars. It sounds crazy, but in a world where magic is returning, maybe he’s the only one who actually knows what’s coming.
The Dance of the Dragons: Their Greatest Power Play
You’ve likely seen House of the Dragon. That’s where House Hightower finally gets the screen time they deserve, primarily through Alicent Hightower and her father, Otto. This was their moment. Otto Hightower served as Hand of the King to three different monarchs. He was the ultimate bureaucrat, the kind of guy who knows exactly which lever to pull to make a king move.

He didn't want a dragon. He wanted his blood on the throne.
- Alicent Hightower: She wasn't just a "mean girl" in the Red Keep. She was the architect of the Green faction.
- The Strategy: By marrying into the Targaryen line, the Hightowers effectively tried to "tame" the dragons through politics and religion.
- The Cost: The civil war nearly wiped out the Targaryen dragons, which, if you’re a conspiracy theorist, might have been the Hightowers' plan all along.
There is a long-standing "Grand Maester Conspiracy" theory among readers. It suggests that the Citadel—controlled by the Hightowers—purposely orchestrated the death of the dragons because magic is unpredictable and dangerous to an ordered society. They want a world governed by logic, math, and the Faith. Dragons don't fit into that equation.
Why They Weren't in the Main Game of Thrones Show
It’s a bit of a sore spot for book fans. In the HBO show Game of Thrones, House Hightower is barely mentioned. We see the Citadel, and we see Samwell Tarly go to Oldtown, but the family itself is strangely absent. In George R.R. Martin’s A Song of Ice and Fire novels, however, they are currently preparing for a massive showdown.
Euron Greyjoy is sailing toward Oldtown.
He’s bringing blood magic and a fleet of ironborn. The Hightowers are calling in their banners. Lord Leyton’s sons are outfitting ships and strengthening the defenses. There’s a palpable sense of dread in the later chapters of A Feast for Crows. The Hightowers have stayed safe for thousands of years by being smarter than their enemies, but Euron is a different kind of monster. He doesn't want their gold; he wants to bring the apocalypse.

Their Words and Sigil: More Than Just a Light
"We Light the Way."
It’s one of the best mottos in the series because it’s a double entendre. Yes, they have a giant lighthouse. But they also "light the way" for humanity through the Citadel and the Faith. They see themselves as the guardians of civilization. While other houses are fighting over who gets to sit on a chair made of swords, the Hightowers are thinking about the next thousand years.
They are traditionalists. They are deeply religious. They are conservative in the truest sense of the word—they want to conserve the status quo because they are at the top of it.
What You Probably Didn't Know About Them
- Gwayne Hightower: In the Dance of the Dragons, he was the second-in-command of the City Watch.
- The High Septon: For centuries, the head of the Faith was almost always a Hightower or someone they hand-picked.
- Lynesse Hightower: She was Jorah Mormont’s wife. He went into debt trying to buy her the luxuries she was used to in Oldtown, which eventually led to him being exiled. This one marriage literally changed the course of Daenerys Targaryen’s life.
- Gerold Hightower: Known as the White Bull, he was the Lord Commander of the Kingsguard under Aerys II. He died at the Tower of Joy. Even in the Kingsguard, the Hightowers were at the pinnacle of power.
The Mystery of Battle Island
The base of the Hightower is the biggest enigma in Westeros. It’s a fortress of black stone, ribless and plain. It doesn't look like First Men architecture. It doesn't look like Andal architecture. Maester Quillion suggested it was built by the "Deep Ones," a race of half-human sea creatures. If House Hightower is sitting on top of an ancient, eldritch bunker, it explains why they are so protective of their home.
They aren't just protecting a city. They might be guarding a secret that could break the world.
Actionable Insights for Fans and Lore Hunters
If you want to truly understand the depth of House Hightower, you need to look past the surface-level politics. They represent the "soft power" of Westeros.
- Watch House of the Dragon Season 2 and 3: Pay attention to how Otto Hightower uses the Faith of the Seven to delegitimize Rhaenyra. This is the Hightower playbook: use culture and religion as weapons.
- Read "The Forsaken" Chapter: If you can find the sample chapter from The Winds of Winter, it paints a terrifying picture of what is coming for Oldtown.
- Visit the Citadel in Lore: Research the "Maester’s Conspiracy." It changes how you view every "accident" that happens to a Targaryen dragon.
- Analyze the Architecture: Look at the descriptions of the Hightower versus the Red Keep. One is a messy fortress; the other is a beacon of engineering.
House Hightower is the reminder that in the world of Game of Thrones, the person with the loudest voice isn't always the one in charge. Sometimes, it’s the person sitting in a library, miles away, counting coins and reading old scrolls. They’ve survived the Long Night, the Andal Invasion, and the Targaryen Conquest. Don't bet against them surviving whatever comes next.
