The royal sept or castle sept is a sept located within the Red Keep, the castle in King's Landing. Also located in the city is the larger Great Sept of Baelor.
The sept is located across the yard from the Red Keep's stables, above the castle's serpentine steps. The Maidenvault is found behind the sept.

Sansa had never seen the sept so crowded, nor so brightly lit; great shafts of rainbow-colored sunlight slanted down through the crystals in the high windows, and candles burned on every side, their little flames twinkling like stars. The Mother's altar and the Warrior's swam in light, but Smith and Crone and Maid and Father had their worshipers as well, and there were even a few flames dancing below the Stranger's half-human face ... for what was Stannis Baratheon, if not the Stranger come to judge them?—thoughts of Sansa Stark
