Qumran

The Essenes were monastic, staying at monasteries like the great Essene complex at Qumran near the Dead Sea. (Hillsdale College - Ancient Christianity)

The Dead Sea Scrolls were discovered between 1947 and 1956 in 11 caves near Khirbet Qumran on the northwestern shores of the Dead Sea.

Also discovered at Qumran, the Essenes had reckoned some of the Hagiographa as canonical and did so before the 2nd century rivalry began.
