Vault Collapse Earthquake Open site page in a new tab
The Italian excavations beside the Main Colonnaded Street revealed a destruction layer where Roman vaults had collapsed onto bedrock, apparently ending the use of the tavern-thermopolium complex (Baldoni, 2019:121). The sealed deposit contained 6th to early-7th century ceramics and 65 bronze coins possibly left as a hoard (Baldoni, 2019:122 and Baldoni, 2018:26). The absence of later Umayyad material suggests that the destruction was likely caused by one of the Jordan Valey Quake(s) of 659/660 CE. The damage occurred within a commercial zone set into the sustaining wall of the lower terrace of the Temple of Artemis, where the collapsed vaults abruptly sealed a functioning thermopolium. After the earthquake, the site appears to have been abandoned.
