Most of Amman's noteworthy historical sites are clustered in the downtown area, which sits at the bottom of four of Amman's seven hills, or jabals.
The ancient Citadel, which towers above the city from atop Jabal al-Qala'a, is a good place to begin a tour of the city. The Citadel is the site of ancient Rabbath-Ammon, and excavations here have revealed numerous Roman, Byzantine and early Islamic remains. The most impressive building of the Citadel, known simply as al-Qasr ("the Palace"), dates back to the Islamic Umayyad period.

The Citadel is the site of ancient Rabbath-Ammon, and excavations here have revealed numerous Roman, Byzantine and early Islamic remains. The most impressive building of the Citadel, known simply as al-Qasr ("the Palace"), dates back to the Islamic Umayyad period. Its exact function is unclear, but it includes a monumental gateway, an audience hall and four vaulted chambers. A colonnaded street also runs through the complex. To the north and northeast are the ruins of Umayyad palace grounds.
Close to al-Qasr lie the remains of a small Byzantine basilica. Corinthian columns mark the site of the church, which is thought to date from the sixth or seventh century CE. About 100 meters south of the church is what is thought to have been a temple of Hercules, today also known as the Great Temple of Amman. The temple was built in the reign of the emperor Marcus Aurelius (161-180 CE), and is currently under restoration.
Also on Citadel Hill, just northwest of the Temple of Hercules, is the Jordan Archeological Museum. This small museum houses an excellent collection of antiquities ranging from prehistoric times to the 15th century. There is an exhibit of the Dead Sea Scrolls, a copy of the Mesha Stele (see Madaba section for explanation) and four rare Iron Age sarcophagi. Museum hours are 08:30-17:00 daily. On Fridays and official holidays the museum is open from 09:00-16:00.
