What is the name of the city ruled by Gwyn in Dark Souls?

Anor Londo is the city ruled by Gwyn in Dark Souls.

The game presents Anor Londo as the grand, sunlit city associated with Gwyn, Lord of Cinder, and the gods of the Age of Fire. The player reaches it after progressing through Sen’s Fortress. Its monumental architecture, enormous halls, painted chamber, and famous rooftop approach make it one of the game’s most recognizable locations.

Anor Londo is also the setting for the boss battle against Dragon Slayer Ornstein and Executioner Smough. After that encounter, the player can meet Gwynevere and receive the Lordvessel, an important object needed to progress toward the game’s endgame objectives.

New Londo is a separate ruined settlement, while Lost Izalith is linked to the Witch of Izalith and the Chaos Flame. Oolacile appears mainly in the Artorias of the Abyss content. These names are often confused because they are all major locations in the same fictional history.
