A Lighthouse is a building which can be used to light up the days and nights when the light is on. The most important part is the top where the Lamp is. If you fill the lamp with a liquid and light this liquid, the lamp will be on and the lighthouse will work.
There are also two other parts of the lighthouse: the lighthouse base and the lighthouse middle parts. These are used to make the light go higher.
Currently only one type of lighthouse is in: the Stone Lighthouse.
