(CNN) — Archaeologists believe they have found the remains of the ancient Greek fort of Acra, solving “one of Jerusalem’s greatest archaeological mysteries.”

The stronghold ruins were unearthed from beneath a parking lot in Jerusalem, Israel’s Antiquities Authority said.

Acra dates back more than 2,000 years, to the time of Greek ruler Antiochus IV Epiphanes.

Excavation directors Doron Ben-Ami, Yana Tchekhanovets and Salome Cohen called it a “sensational discovery.”

“The new archaeological finds indicate the establishment of a well-fortified stronghold that was constructed on the high bedrock cliff overlooking the steep slopes of the City of David hill,” a statement from the team said.
