Harrenhal

Harrenhal, the largest castle in the Seven Kingdoms, is the seat of House Whent in the riverlands, on the north shore of the Gods Eye. Since the burning of Harrenhall by dragonfire in Aegon's Conquest, however, the castle has become a dark and ruinous place. Harrenhall's holdings are some of the richest in Westeros, claiming vast tracts of green fertile land which reach as far as the hills of House Wode near the crownlands.
