In the 10th century BC, King David of the Jews led tribes to occupy Jerusalem and established the Jewish State of Israel as the center of their rule. Later, Solomon, his son, built a temple on Mount Zion in Jerusalem. In the sixth century B.C., the temple was burned by invading Babylonians, rebuilt half a century later, and then destroyed. The last one was rebuilt by Herod I in 35 B.C. and named Herod's Temple. By AD 70 and 135, the temple was burned down again by the Romans. The 12-metre-high west wall was restored on the foundation of the West courtyard after the temple was burned down. The crying wall, also known as the West Wall, is a section of the second temple wall of the ancient Jewish State in the Old City of Jerusalem. It is also the only remaining site of the second temple wall. It is about 50 meters long and 18 meters high. It is made of large stones. Judaism regards the wall as the first holy place. For thousands of years, when Jews living in various corners of the world returned to the holy city of Jerusalem, they would come to this stone wall to pray in low voice and cry out about the suffering of exile, so it is called "the wall of crying". According to Jewish tradition, prayers under the Western Wall go straight to heaven. So the people who come here will write their wishes and prayers into small notes and put them in the cracks of the western wall.
