House Hightower is an old, wealthy noble family from Oldtown in the Reach, and in House of the Dragon they matter mainly because of Otto and Alicent Hightower. They’re tied to the “Greens” side of the Targaryen civil war, the Dance of the Dragons.

Quick Scoop

  • Seat: Oldtown, one of the oldest and richest cities in Westeros.
  • Sigil: A white watchtower with a fire on top.
  • Words: “We Light the Way”.
  • Why they matter: Otto Hightower is a major political player, and his daughter Alicent becomes queen and helps drive the conflict.

In plain English

If House Targaryen is the dragon-riding royal family, House Hightower is the powerful old aristocratic house backing the other side of the family feud. They’re not the flashy dragon house, but they’re influential through money, religion, politics, and Oldtown’s prestige.

Tiny lore note

In the wider Game of Thrones world, the Hightowers don’t get as much screen time, but they’re still one of Westeros’s most ancient houses. Their name comes from the great Hightower in Oldtown, which is central to their identity.

TL;DR

House Hightower is basically the powerful Oldtown family in House of the Dragon — rich, ancient, politically savvy, and central to the Greens’ rise.
