The Fall of Harrenhal

Harrenhal was the seat of one of the most powerful Kings of Westeros before Aegon the Conqueror united the Seven Kingdoms. With its immensly high and impossibly thick walls, Harren thought himself untouchable. He had not anticipated Aegon's dragons, however. Their fire scorched and burned the buildings, giving them a molten look, and roasted Harren and his kin inside its very walls.
