What is the importance of Kingsbridge in the novel, A Column of Fire?

Kingsbridge is where the novel both begins and ends in a literal and narrative sense. It is where Ned, Margery, and Rollo are introduced and eventually leave in an effort to bring their beliefs back into power. Kingsbridge is the first example of corruption within the Catholic church through the actions of Bishop Julius, Sir Reginald, and the torturous execution of Philbert Cobley. All of the English main characters return to this location many times throughout the novel, as it is their home and the place they care the most about. After Elizabeth takes the throne, Kingsbridge becomes politically important, as Ned tries to promote tolerance against the radical Catholics and Puritans who believe in the death of others. By the end of the novel, Kingsbridge is where Ned returns to live out the rest of his life. Presumably, his grave is there near his family and Margery, the love of his life.
