After he emerged victorious and united the Seven Kingdoms, he started building the Red Keep. This location features prominently in House of the Dragon season 1, as it served as the jumping off point for Aegon I’s conquest of Westeros. The Crownlands is comprised of King’s Landing, the area surrounding the city, Blackwater Bay, and the castle of Dragonstone - culturally defined mainly by its nature as the continent’s capital. It’s also home to Harrenhal, the largest and most unwieldy castle in Westeros, as well as the historically significant God’s Eye lake and its Isle of Faces, which served as the site of the peace treaty between the First Men and the Children of the Forest after the two ended their ancient conflict thousands of years before. In addition to the handful of significant battles that took place there in Game of Thrones season 2, it’s also home to the seat of House Frey, The Twins - the site of the Red Wedding and subsequent end of the Stark Rebellion. Apart from being a crucial location during the Targaryen Civil War in House of the Dragon, the Riverlands notably hosted the conflict between the Tullys and the Lannisters in Game of Thrones season 1, serving as the main theater for the War of the Five Kings. The Riverlands lie directly to the east of the Westerlands - just north of King's Landing - and its ruling family is House Tully, whose castle, Riverrun, was the childhood home of Catelyn and Lysa Tully.
