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.[1][2] 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.[3] There is however a public footpath that runs alongside the castle mound and up a hill to give a reasonable view.
