What little remains of the castle at Odell stands beside the church on high ground above the village green. The castle was built by Walter Flandrensis, a Norman adherent of William the Conqueror.
William granted large tracts of land to Walter, including the manor of Wahull, as the village was then called. Walter settled here and called himself Baron of Wahull. He built the castle, and the family lived here for some 400 years before the title died with a succession of female heirs. The castle fell into disrepair and finally disintegrated into ruins.
