Masada Fortress was the professor of the Hebrew University of Jerusalem, Iguo Aden, who led the archaeological team from 1963 to 1965. Most of the buildings here were built during the Herod period. Although it is now desolate by the wind and the sun, it still can see the remains of baths, reservoirs and so on. Masada is the last castle of the Jews. After the fall of , the Jewish nation's footprint disappeared from the land of Canaan and began to be displaced for thousands of years. At that time, it was said that it was a lot of manpower and material resources. When it was built, it can be said to be extremely luxurious. But these can't be enemies with the sky. Water shortage is the biggest problem here. Finally, Herod has a total of 12 reservoirs in the castle, each with a capacity of up to 4,000 cubic meters. Therefore, the castle in the desert is not only self-sufficient in drinking water, but also satisfies the luxury of the desert, such as bathing and swimming.
