A 1,400-year-old well has been uncovered near Tel Aviv.

The finding is being called “top of the line” by researchers at the Israel Antiquities Authority, due to the well’s excellent preservation for its age.

The well was unearthed at Ramat Hahayal during a dig ahead of a construction project for a new medical center. The ancient well is said to have been used in both the Byzantine and Early Islamic periods.

“This finding, called Antilla, which has now been uncovered for the first time in Tel Aviv, adds information about aspects of everyday life in the Yarkon 1,400 to 1,200 years ago, including agriculture,” said Elie Haddad, director of the excavation for the Israel Antiquities Authority.

Historians said the well is an advanced system for its time period, as it uses a pump mechanism to bring water to the surface.
