Until today, lighthouse navigation is still a reliable way. In the 5th century BC, the Greeks knew to use lighthouses to indicate ports at night. Lighthouses appeared in the Mediterranean much earlier than in Greece. The earliest lighthouse in the world was built in the 7th century BC, located at Baba Point in the Da Daniil Strait, which looks like a huge bell tower. People burn firewood in the container of the lighthouse and use its fire to guide the course. In 280 BC, the ancient Egyptians were ordered by the king to build a lighthouse on fallows Island opposite Alexandria, Egypt, which was 85 meters high and burned firewood day and night, marked by flames and smoke columns. The lighthouse was later destroyed by the earthquake.

Early lighthouses were built of wood and stone, and later developed into iron structures and concrete structures. Most of the time, candles are luminous, and candlelight is reflected by a simple metal mirror. Among the ancient lighthouses still in use today, there is the Livorno Lighthouse in Italy, which is 50 meters high and 1304 is made of stone.

1784, someone invented a fuel device suitable for lighthouse, which consists of a wick and a parabolic metal mirror. 1822 someone has made a lens that can gather and project light beams and effectively improve the lighting of the lighthouse. The electric lighthouse appeared in 1858. 1885 caisson method was first used to build lighthouse on soft foundation. 1906 the first gas flash tower was built.

In 1850, there were only 1570 lighthouses in the world, and in 1900, the number increased to 9400. By the early 1990s, there were more than 55,000 lighthouses, including other luminous lighthouses. Lighthouses shine on every corner of the sea and guide the lost sailors. This historic lighthouse is still a reliable and effective navigation sign.
