The Large Oak Tree was a tree to the west of Castle Daventry just across the moat, and west of the garden. A very pretty maple tree and a small thicket of unimpressive white birch trees grew nearby. During Graham's quest to find the three lost treasures of Daventry, he climbed the tree finding a large Golden Egg laying in a nest in its branches. Children of Daventry could often be seen playing in its branches. It is one of two trees in the area that has delighted vistorss for generations. They both yield golden treasures.
