Thou shalt not remove thy neighbour’s landmark, which they of old time have set in thine inheritance, which thou shalt inherit in the land that the LORD thy God giveth thee to possess it.
This verse tells us a lot about what God thinks about landmarks.
A landmark is a mark to designate the boundary of land. (fixed object, marked tree, stone, wall, fence, river or body of water, etc.) In navigation, it is any elevated object on land that serves as a guide to seamen, (lighthouse).
