The Wailing Wall, also known as the Western Wall, is a section of the protective wall of the Second Temple of the ancient Jewish State in the Old City of Jerusalem. It is also the only remaining site of the protective wall of the Second Temple. Judaism regards the wall as the first holiest site and is the most popular among believers. The wall must be mourned to express condolences for the ancient temple and look forward to its restoration. The Wailing Wall is about 20 meters long and 50 meters long. It is separated by a screen in the middle. When praying, men and women are different when entering the square wall. Men must wear traditional hats. If there is no hat, paper hats are also provided at the entrance. Many lingering prayers touched the wall with their hands, recited scriptures, or stuffed slips of paper with prayer words into the cracks of the wall. After thousands of years of wind and rain and the touch of pilgrims, the stones of the Wailing Wall are also glowing, as if weeping and complaining. Tower of David The Tower of David is the highest point in the Old City of Jerusalem, located in the Jewish Quarter near Joppa Gate. This city tower was built by King Herod about 2,000 years ago. The ancient Hamo Wall and three city towers including the Tower of Phasel, the Tower of Hippicus and the Tower of Miriani have been excavated one after another. , as well as architectural remains from the Roman, Byzantine, Crusader and Turkish eras. The Tower of David was the palace built by King Herod the Great and a fortification on the west side of Jerusalem. There are three giant towers on the fortress, each named after Herod’s brother Phasenus, his friend Hippicus, and his wife Mary Anne, who was murdered by Herod. In AD 70, Emperor Titus used this magnificent castle palace as the military camp of the Roman Tenth Legion to show the power and bravery of the Roman army. Below the castle, you can still see the remains of the Herodian era. In the 12th and 14th centuries, the Crusaders and Egyptian Muslims rebuilt the castle respectively. The remaining fortress was built by King Suliman of Turkey in 1540. . Dead Sea The Dead Sea is an inland salt lake located in the Jordan Valley between Israel and Jordan. The west bank is the Judean Mountains, and the east bank is the Transjordan Plateau. The Jordan River enters from the north. The Jordan River injects 540 million cubic meters of water into the Dead Sea every year. There are also four small but perennial rivers that inject water from the east. Due to the large amount of evaporation in summer and the injection of water in winter, the level of the Dead Sea changes seasonally. From 30 to 60 cm. The Dead Sea is 80 kilometers long, 18 kilometers wide, with a surface area of about 1,020 square kilometers, an average depth of 300 meters, and a deepest depth of 415 meters. The Lisan Peninsula in the east of the lake divides the lake into two lake basins of different sizes and depths. The northern one accounts for three-quarters of the area and is 415 meters deep, while the southern one has an average depth of less than 3 meters. There is no outlet. The main water intake is from the Jordan River. The water intake is roughly equal to the evaporation. It is one of the natural water bodies with the highest salinity in the world. The sea, lakes and anchorage shores are rich in salt. In such water, it is difficult for fish and other aquatic organisms to survive. There are only bacteria and no organisms in the water; there are also no organisms on the shore and surrounding areas. Flowers and plants grow, so people call it the “Dead Sea”.
