House Towers of Harrenhal was a noble house from Harrenhal in the riverlands. They blazoned their arms with five black towers on white, a double tressure red and black.
After King Maegor I Targaryen wiped out House Harroway in 44 AC he decreed that the strongest of his knights would have the castle of Harrenhal. Twenty-three knights fought in the blood-soaked streets of Lord Harroway's Town for the prize. Ser Walton Towers, though gravely wounded, was the victor. He was named Lord of Harrenhal, though he died soon after from the wounds he had taken in the battle. House Towers failed two generations later, after which King Jaehaerys I Targaryen granted Harrenhal to House Strong.
