HighGarden

 

Highgarden is the seat of House Tyrell and the regional capital of the Reach. It is next to the river Mander. Highgarden sits on the point where theRoseroad linking Oldtown and King's Landing forks off west on the Searoad which leads to Lannisport. As King's Landing, Oldtown, and Lannisport are the first, second, and third largest cities in Westeros, heavy trade and traffic to and from Oldtown ultimately passes through Highgarden.

Highgarden was originally the seat of House Gardener, founded by Garth Greenhand one of the legendary kings of the First Men. House Gardener ruled as the Kings of the Reach until the invasion of Aegon the Conqueror. King Mern IX Gardener and all his issue were slaughtered by Aegon'sdragons on the Field of Fire, so Aegon raised the Tyrells, the stewards of Highgarden, to rule over Highgarden and the Reach. This sparked off a long-standing complaint from House Florent of Brightwater Keep, who claimed a superior blood-link to the Gardeners, though this has been constantly dismissed by later kings.
