Lighthouses are erected on unused plains and increase the range of sight. The higher the level of the building the higher is the range of sight. At strategically important points this allows to keep an eye on your borders.
If a lighthouse is sabotaged, its range of sight is 2 fields during the sabotage, like all other fields.
