The Definitive Glossary for Game of Thrones

As the home to many great houses over centuries, Harrenhal has a rich history that spans the entirety of the formation of the political system of the seven kingdoms. Residing in the Riverlands, it is grand in size and has five massive towers obscured from view by monstrously huge walls. It has walls so thick it appears the castle got created by giants. With a size that tops Winterfell by three times, it became a popular site for hosting events, most notably, the great council of 101 AC. Though it is a sheer monstrosity in size, most of its elegance faded off as it got destroyed by Aegon the Conqueror.

Physical Description

Harrenhal is a colossal structure that towers every castle in the seven kingdoms when placed side by side, making it the largest castle in the seven kingdoms. It has a chamber room that is so large that it appears as though it got created for giants, and its stables can house more than a thousand horses. Its godswood is the largest in the realm, covering twenty acres. Though mighty in size and an architectural wonder to many, most of Harrenhal lies in decay and rot, as more than half of the castle’s space got abandoned after Aegon Targaryen’s destruction.

Harrenhal houses five great towers, the smallest being half the size of Winterfell’s tallest. Though they can barely be seen from outside the castle, as the walls cover most of it, they still are a marvel to behold. The towers lean to the side because the fire from Aegon’s dragon Balerion destroyed portions of the walls. After Aegon’s destruction of the castle, the old names of the towers got lost in history, and they got new ones, Tower of Dread, Widows Tower, Wailing Tower, Tower of Ghosts, and Kingspyre Tower.

On either side of the enormous castle are two gates, the primary and eastern gates. The walls of the main gates are so thick that to walk its length will entail passing more than a dozen murder holes. The second gate is smaller but still massive compared to most castle gates.

Other Features of the Castle

Besides towering walls and gigantic towers, there are many other impressive works of architectural design in Harrenhal’s houses. Some of them are:

  • The kitchen is so huge that they compare in size to Winterfell’s Great Hall.
  • The Hall of the Hundred Hearts is the Great Hall. It can house an entire army and has steps to two galleries.
  • A Bathhouse large enough to contain six to seven people at once.


Though a castle of magnificent size, Harrenhal has one of the darkest histories in the seven kingdoms and has passed through several noble houses. The great misfortunes it suffered over the years made people believe it was cursed.

Chronology of Houses that Inhabited Harrenhal

House Hoare

Harrenhal got created by the extinct House Hoare, who at the time ruled the Iron Islands. Before its creation, the house placed its seat at a modest tower house at Fairmarket on the Blue Fork. After the death of Halleck Hoare, his son, Harren the Black, decided to build a castle so grand none other would measure in its magnitude and magnificence.

Set out to fulfill his dream, Harren took forty years to construct Harrenhal. Thousands got killed, and many froze while working on the construction. Weirwoods got destroyed, and many got used as support beams. After the completion of the fortress, Harren boasted about its invulnerability. However, Aegon’s arrival in Westeros changed everything as his dragon Balerion the Black Dread, roasted Harren alive within the walls of his castle with Dragonfire

House Qoherys

After Aegon’s destroyed the castle, he granted the remnant to Quenton Qoherys of House Qoherys. However, the house went extinct during Aenys I Targaryen’s rule when Lord Gorgan, Quenton’s son, got murdered for attending Harren the Red’s wedding and claiming the Lord’s right to the first night.

House Harroway

After Lord Gorgan’s death, Lord Lucas Harroway took charge of Harrenhal. During the Battle Beneath the God’s Eye, House Harroway helped to defeat Aeny’s son, Aegon. They later got wiped out by Maegor I Targaryen.

House Towers

After destroying House Towers, Maegor the Cruel declared that the strongest of his knights would gain ownership of Harrenhal; this sparked a blood-drenching battle between twenty-three knights. In the end, an injured Ser Walton won and received the castle. However, he died two weeks after his victory.

House Strong

After House Towers, House Strong took control of Harrenhal. The house controlled the castle for two generations and supported Aegon II during the Dance with Dragons. However, Lord Lyonel Strong and his heir, Ser Harwin Strong, died in a mysterious fire secretly arrange by Larys Strong inside the castle; this sealed its position as a cursed place.

House Lothston

After Aegon III became king, he gave the castle to Ser Lucas Lothston. During the first Blackfyre Rebellion, Manfred Lothston sided with Daemon Blackfyre, and the second rebellion got suppressed by Danelle Lothston. However, the Lothstons went extinct after Danelle went mad.

House Whent

After aiding in the Lothston’s defeat, House Whent became the Lord of Harrenhal. In 281 AC, Lord Walter Whent hosted a tourney where Rhaegar Targaryen, Prince of Dragonstone, was crowned the champion. The tournament got famous for the appearance of the Knight of the Laughing Tree and the naming of Ser Jaime Lannister as member of the kingsguard to Aerys II Targaryen.
