This citadel houses the ancient structures and architectural ruins that have been well preserved to make people aware of the history and culture of Amman. Another striking sight here is the Umayyad palace that was constructed in the 8th century, and now it is in a completely ruined state. It also houses a Byzantine Church that dates back to around 5th century AD and a National Archaeological Museum that houses an interesting collection of artifacts from the different eras of Jordan.
