1. London
      Caer Lludd, Caer Lundein, Caer-Lundene, Laidon, Londen, Londres, Londrez, Lounde, Lunden, Lundres

      The capital city of Great Britain.

      It was allegedly founded by Brutus, who named the city Troia Nova, which means 'New Troy'. The city subsequently became the capital of Lludd, the sixty-eighth ruler after Brutus, who fortified the walls, at which time it was known as Caer Lludd, 'Lludd's Fort', Caer Lundein. Some time later the 'Caer' was dropped, and the city simply became known as Lundein, of which the modern name is a simple derivation.

      This must have been a good place to buy armor: Cligés sent his squires here from Wallingford to buy three full suits of it - one black - one crimson, and one green - for him to wear in the Oxford tournament. They accomplished this within a fortnight.

    2. London Bridge

      In one version of Tristrams Kvĉdi, an Icelandic ballad, Tristan receives his mortal wound while battling a "heathen dog" on London Bridge.

    3. London Cathedral

      In Malory this can be read:

      So in the greatest church of London, whether were Paul's or not the French book maketh no mention, all the estates were long or day in the church for to pray [for the choice of a king].

      "Paul's" would of course be old St. Paul's cathedral.
