Its salt and mineral content is 30% to 40% while the normal ocean’s salt content is around 6%. Only about 2 inches of rain fall each year, but there are occasional and fierce thunderstorms. The sea is called “dead” because its high salinity means no macroscopic aquatic organisms such as fish or water plants can live in it, though minuscule quantities of bacteria and microbial fungi are present. The human history of the Dead Sea goes all the way back to remote antiquity. Just north of the Dead Sea is Jericho, the oldest continually occupied town in the world.
The most famous was Masada, where, in 66-70 AD, a small group of rebellious Jewish zealots held out against the might of the Roman Legion, and Machaerus where, it is believed John the Baptist had been imprisoned by Herod Antipas and met his death. The name of the Dead Sea’s Mount Sodom comes from the biblical story of Sodom and Gomorrah. The Dead Sea is the lowest point of the Earth, therefore, became a significant touristic destination. The Dead Sea is one of gateways of travelling to Jordan and Judea-Samaria (also known as the West Bank). Biblical towns such as Be’er Sheva, Jericho, Bethlehem are not far from the Dead Sea.
