Synagogue unearthed in Russia may be one of the oldest outside Israel. But not everyone is convinced.

Archaeologists in southern Russia say they’ve found the ruins of a 2,000-year-old synagogue — a uncommon discovery on condition that buildings for Jewish worship from this era are seldom discovered outdoors the Holy Land.

The group made the invention just some miles east of Crimea on Russia’s Taman Peninsula, the place they’re excavating the stays of an historical Greek colony on the Phanagoria archaeological web site. The synagogue’s age hasn’t but been verified in a peer-reviewed examine,  however it could date to greater than 100 years earlier than the Second Temple in Jerusalem was destroyed by Roman legions in A.D. 70.
