The Challenge: Identify items on Syrian banknotes

I am cataloging the Central Bank of Syria's notes for publication in The Banknote Book, and I have been unable to identify a few items which appear on these notes.

The back of the 100-pound note dated 1966-1974 depicts a dam. What's the name and location of this dam?

The front of the 5-pound note dated 1977-1991 depicts a female statue.
IDENTIFIED: Allāt-Minerva. Statue of the 2nd century AD from As-Suwayda, Syria (Roman province). National Museum of Damascus.

The front of the 50-pound note dated 1977-1991 depicts a female statue.
IDENTIFIED: Statue of goddess found in Sumerian ruins in Mari, Syria, now in National Museum of Aleppo.

The back of the 500-pound note dated 1958-1992 depicts something described as an ancient religious wheel.
IDENTIFIED: Gold bowl decorated with hunting/animal scenes from the Temple of Baal at Ugarit, now in National Museum in Aleppo.

If anyone has information or leads which may be helpful, please contact me with details.
