Castle Hill is the commanding heights of Amman. It used to be the first fortress in Amman and is closely related to the history of Amman. From the 11th century BC, the kingdom of Amon, who worshipped the Egyptian sun god, built the capital on the Castle Hill. Later, 300 years before the park, the Macedonian kingdom built Philadelphia again. Later, the Arabs built the Amir Palace. Today, in the Castle Hill you can see the three walls of the era, they witness the historical changes of Amman. Castle Hill is also the best place to overlook Amman. Ascend to the top of the mountain, the entire Amman city is high and low, and the rows of white buildings are in front of you. You will have a more perceptual understanding of the reputation of Amman's "White City".
