Excavations carried out on Mt. Zion have found a destruction layer dating to the 12th century C.E., when Baldwin III stormed the crusader citadel in order to wrest power over Jerusalem from his mother, Queen Melisende.
The intriguing layer of black ashy deposits, dated to around 1153 C.E., was discovered on the west side of the excavation site on Mt. Zion by the University of North Carolina at Charlotte this summer, led by Shimon Gibson, James Tabor and Rafi Lewis.
That said, a coin found in this layer was identified by coins expert Robert Kool of the Israel Antiquities Authority as belonging to the “rough series” of coins issued by Baldwin III, possibly starting in 1152 or 1153. The coin attributed to Baldwin III raises an interesting historical episode. It was in 1152 that Baldwin III (who reigned from 1143-1163) came to Jerusalem, to wrest power from his mother, Melisende, Queen of Jerusalem from 1131 to 1153 through no design of her own. Melisende at the time was residing in the palace next to the citadel on the west side of the city.
