Why can Alexander Lighthouse be one of eight wonders of the world?

Because it was built in 28 1 year BC, the lighthouse was always on until 64 1 year AD, when the Islamic army of Arabs conquered Egypt, the flame went out, and it stood for 922 years before and after, and was destroyed by the earthquake. However, in the long historical process, the flame on the lighthouse has been burning for nearly a thousand years.

This is a rare feat in human history. Imagine a flame burning day and night by countless people. It needs the concerted efforts of countless generations of Qi Xin. It has experienced various natural disasters and wars, including rain and snow, but the fire never went out. According to various historical records, it has been burning vigorously until the earthquake many years later, which was really force majeure and finally led to destruction and extinction.

The lighthouse itself was built on three huge stone steps. During the day, a mirror is placed at the top to reflect sunlight, and it is used to make a fire at night and burn it all night to guide the ship's navigation and prevent the ship from getting lost during the voyage. This is also the main function of the lighthouse.

Even on the inclined steps leading to the middle and upper floors, there are 32 and 18 stone steps respectively, and a manual lifting mechanism equivalent to an elevator is placed in the middle, which is responsible for transporting torch fuel and various materials for vigil on the lighthouse, so as to ensure that the torch does not go out day and night all year round.

Besides its symbolic meaning, the torch is also equipped with a concave metal mirror, which can reflect bright fire and sunshine during the day and can tell the direction of ships 60 kilometers away at the farthest, so it is called "one of eight wonders of the world".
