Israeli archaeologists have announced that ruins long thought to be of an ancient synagogue are actually the remains of a palace built by Arab caliphs 1,300 years ago.

The site, on the banks of the Sea of Galilee, was identified as a synagogue in the 1950s because archaeologists found a carving of a menorah, a seven-armed candelabra that is a Jewish symbol. But scholars said in a report published this week that the identification was an error, and that the site was a winter palace used by the caliphs of the Umayyad dynasty, the same rulers who built Jerusalem's gold-capped Dome of the Rock.

Early Arab historians had described the palace, calling it al-Sinnabra, but its location was previously unknown.
