Pendragon

The Holy capital of Brittania Or Just The holy Capital

The capital of the Empire is the Imperial Capital of Pendragon, where Pendragon Palace is situated. It was a city of lights that gleamed in the nights sky.The city was destroyed by Schneizel using his F.L.E.I.J.A. equipped floating fortress, Damocles. The majority of the ruling faresides in the district of the capital known as "Saint Darwin Street",

The Emperor apparently resides in "Britannia Palace", the site of the assassination, as well as Lelouch's temporary residence at the time of his reign. Other residences in the capital include: Belial Palace where Nunnally resided in the year between the first and second seasons; Warrick Palace, the home of Clovis' mother, Gabriella la Britannia and the Imperial Villa at Aries (アリエスの離宮|Ariesu No Rikyū), the residence of Lelouch's mother prior to her death. Owing to his fond childhood memories of the beautiful aerial gardens at Aries, Clovis La Britannia later modeled the villa on top of the Viceroy's Palace in Area 11 after it. The Britanian homeland of Pendragon appears to be in the middle of our present day Mexico and United States. Pendragon Palace is the center of government for the Britannian Empire has many luxuries including many conference rooms, quarters, living areas, and a throne room.
