Pendragon

The Pendragon Imperial Palace is the capital of the Holy Britannian Empire. It was a city of lights that gleamed in the night sky. The city was destroyed by Schneizel el Britannia using a F.L.E.I.J.A. warhead from aboard Damocles. The majority of the Britannian Imperial Family reside in the district of the capital known as "Saint Darwin Street". Pendragon appears to be in the middle of in the real-world, as indicated by the surrounding mountains and desert.

Emperor Charles resided in the "Britannia Imperial Palace", the site of his assassination, as well as Lelouch's residence at the time of his own reign. Other residences in the capital include:
 * Belial Palace, where Nunnally vi Britannia stayed between 2017 and ;
 * Warwick Palace, the home of Clovis' mother, Gabriella la Britannia;
 * 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 atop the Viceroy's Palace in Area 11 after it.
 * Exelica garden, a garden inside the palace where Lelouch and Suzaku received notices from the rebellion leaded by the knight of one.
