After visiting the world heritage site, the ruins of the ancient city of Jerash, he rushed to Amman, the capital of Jordan, to visit the Castle Hill. In the setting sun, the Castle Hill of the ancient Roman ruins and the Jordanian capital shine together, and there is a feeling of crossing time and space. Castle Hill is the best location overlooking downtown Amman. When you climb the summit, you can see the ancient Roman theater at the foot of the mountain, like a half ring inlaid in the city. High-low, staggered buildings lined up in front of you. Overlooking the old city of Amman, the houses are interlaced, and there is no shortage of neatness in the mess. There is no shortage of mottled. A huge Jordanian flag is flying and hunting, this is the largest national flag in the world. The National Archaeological Museum of Amman is in the Castle Hill and is the smallest museum I have seen so far. The Dead Sea Scrolls are the most important antiquities of the museum.
