Location from A Song of Ice and Fire by George R.R. Martin
The seat of House Tyrell — a castle of white stone and climbing roses set amid the most fertile farmland in Westeros, where beauty masks a ruthless talent for political maneuvering.
Highgarden is the most beautiful castle in Westeros and its lords have never let anyone forget it. Everything is cultivated here — the gardens, the food, the courtesies, and especially the alliances. The Tyrells understand that the Reach's true power is not martial but agricultural; they feed the realm, and a kingdom that cannot eat cannot fight. Olenna Tyrell ran the house's political strategy from these gardens for decades, and the scent of roses that permeates every corridor masks the sharp smell of ambition that drives the family. Feasts here last for days. Singers compete for patronage. And behind every smile, someone is calculating how this particular friendship can be leveraged into greater influence.
Graceful white towers rise above terraced gardens that cascade down gentle hills, threaded with fountains and arbors heavy with golden roses. The castle gleams in sunlight, its walls covered in climbing roses that bloom in every color. The surrounding Reach stretches to the horizon in fields of wheat and orchards of fruit.
