Weksler-Bdolah in Galor and Avni (2011:421) reported
that the Roman-Byzantine walls were used continuously until the
mid-8th century, after which they were “partially damaged, probably
by an earthquake” (Weksler-Bdolah 2007:97). Renovations were identified
in several places along its route, showing that the walls remained
in use after this damage. Magness
(1991), re-examining ceramics and numismatics from Hamilton (1944)’s excavations at the Damascus Gate,
established a terminus post quem in the first half of the 8th century
CE for wall repairs, describing the pottery level as “one of the most
securely dated assemblages of published Byzantine and Umayyad pottery
from an excavation in Jerusalem.” In the Armenian Garden, Magness (1991) also analyzed ceramics from Tushingham (1985)’s excavations, redating the
rebuilding of the southwest corner of the city walls from the 7th
century CE to the 8th century CE.
Together, these studies support the interpretation that a mid-8th
century earthquake caused significant damage to Jerusalem’s
Roman-Byzantine walls, prompting subsequent repairs and rebuilding.
