A recent discovery of a stone structure submerged in the Sea of Gallilee (Lake Kinneret) may be the stone structure described by the Arizal (Isaac Luria) and other Jewish sages as the Well of Miriam (Be'er Miriam/ Be'eirah shel Miriam). This was believed to be a place of healing waters. This article mentions its possible connection to the Well of Miriam spoken about by the Jewish sages (Chazal).
"Nautical archaeologists have reported the discovery of a “monumental” conical stone pile built of large, natural, unhewn basalt cobbles and boulders, on the floor of the Sea of Galilee.
The structure is definitely man-made, and measures about 70 meters in diameter at about 219 meters below sea level, reported archaeologists Yitzchak Paz, Moshe Reshef, Zvi Ben-Avraham, Shmuel Marco, Gideon Tibor and Dani Nadel, in the International Journal of Nautical Archaeology...
Researcher Yitzchak Paz, of the Israel Antiquities Authority and Ben-Gurion University, told LiveScience.com the structure could date back more than 4,000 years. The “effort invested in such an enterprise is indicative of a complex, well-organized society, with planning skills and economic ability,” the researchers wrote in their journal paper.
Chazal teach that the well of Miriam came to rest in the Kinneret. The Be’er is described in Medrashim andmeforshim as a stone. Could this stone structure perhaps be the Be’eirah shel Miriam“?.."
