An underground water source was discovered near Jerusalem's International Convention Center that experts say represents the largest subsurface water resource ever discovered in Israel.
The source was discovered 75 meters underground while workers laid groundwork for the high-speed Tel Aviv-Jerusalem railway.
The cave appears to have developed after water seeped in from the surface and dissolved the underlying limestone. "The cave is the largest and most impressive underground water channel ever discovered in Israel," Prof. Amos Frumkin of Hebrew University told Channel 2 News.
Frumkin said the water channel can be preserved without compromising infrastructure projects to construct the rail route.
