about lighthouses
Lighthouses are all by the sea. They help to keep ships safe.
A lighthouse is tall and round like a tower. It has stairs that go round and round up to the top.
There is a big light at the top of the lighthouse. It shines over the sea at night.
People on boats and ships see the big light. It makes them keep away from the rocks.
Lighthouses help ships in bad weather, too. They have horns that make a big noise.
