Castle Bytham, GB
Bytham Castle was a castle in the village of Castle Bytham in Lincolnshire (grid reference SK992186.) The castle is thought to be of early Norman origin. The earthworks, on a hill above the village, are visible but nothing of the stonework is above ground. There is no public access to the monument.
There is however a public footpath that runs alongside the castle mound and up a hill to give a reasonable view.
