Lotz Cisterns (Hebrew: בורות לוץ‎, Borot Lotz‎; the spelling Loz is used, too) is an archaeological site in Negev Mountains, Israel, where 17 ancient water cisterns are located. Of those, about 8 are still filled with water after winter rains. The cisterns are spread over an area of two square kilometers in the vicinity of Mount Ramon. At the site, there is also an ancient pistacia atlantica tree. During the winter and spring months, numerous flowers grow in the area, primarily around sources of water.
