The reopening of Abraham's gate is truly one of Israel's most coveted and significant historical treasures. This gate is the same gate that Abraham passed through while he was on his way to save Lot from the Israelites. The people of Israel find this to be a significant historical treasure because of its historical significance. It describes the event that happened in the biblical times throughout the Bible. 
Abraham's gate was uncovered in 1979 at Tel Dan in the north. This structure was from the Canaanite period of the Bronze Age. It was built around 1750 B.C. The authorities named this archaeological site after Abraham, which is the first patriarch of the Jewish people, because it dates from the period of Abraham. The gate was recently under restoration, and was just reopened to the public. The structure is made of three arches and made from sun-dried mud bricks on top of a foundation of large basalt stones. It stood seven meters tall (twenty-two feet) and has two towers and a horizontal structure linking them below. These arches are the oldest that were ever found in Israel. The gate is almost four thousand years old. "Ze'ev Margalit, who is responsible for archaeological preservation at the parks authority, indicated that 'The Bible recounts that the people of Dan took Abraham's nephew Lot prisoner, and Abraham came to Dan to rescue him.'" 
In Genesis 14:8-12 it says:
"Then the king of Sodom, the king of Gomorrah, the king of Admah, the king of Zeboiim and the king of Bela (that is, Zoar) marched out and drew up their battle lines in the Valley of Siddim against Kedorlaomer king of Elam, Tidal king of Goiim, Amraphel king of Shinar and Arioch king of Ellasar—four kings against five. Now the Valley of Siddim was full of tar pits, and when the kings of Sodom and Gomorrah fled, some of the men fell into them and the rest fled to the hills. The four kings seized all the goods of Sodom and Gomorrah and all their food; then they went away. They also carried off Abram's nephew Lot and his possessions, since he was living in Sodom."
The kings went to Sodom and Gomorrah and took all of their food, Lot (Abraham's nephew), and everything that he owned. They imprisoned him, and kept him to die.
In Genesis 14:13-16 it says:
"One who had escaped came and reported this to Abram the Hebrew. Now Abram was living near the great trees of Mamre the Amorite, a brother of Eshcol and Aner, all of whom were allied with Abram. When Abram heard that his relative had been taken captive, he called out the 318 trained men born in his household and went in pursuit as far as Dan. During the night Abram divided his men to attack them and he routed them, pursuing them as far as Hobah, north of Damascus. He recovered all the goods and brought back his relative Lot and his possessions, together with the women and the other people."
Abraham got all of his people, and they became an army. He split them up and went to Sodom to save Lot. Abraham entered through the gate that is now called "Abraham's Gate" and rescued Lot, his possessions, and all of the women, men, and children.
