Lighthouse Research
Lighthouses were first invented by the Greeks/Romans and was
used around Europe during the medieval era. Lighthouses are still used today
but are a lot more advanced than when they were first built. They were built
due to the increase in the creation of larger boats that could travel further.
These boats would usually use landmarks or piles of rock to make their way to a
place, but this would only be effective during the daytime. During the night
sailors couldn’t see, hence the creation of the lighthouse. It was a tower that
would have a bonfire on top located along a coast or on an island just off the
coast. This would allow sailors to safely navigate the sea during the night.
Once electricity was discovered, electrical lights were used instead as it was
more reliable. This was when lighthouses began being used more. However, a
stable and controlled form of electricity wasn’t invented until 1879 by Thomas
Edison, so up until that point a bonfire was used. They are normally used for
one of two reasons: Either they warn sailors to stay away from a dangerous area
e.g. cliffs, rock piles, while the other gets the sailor to come towards the
lighthouse e.g. if there is a harbour for the boats to dock at.
