Dol Guldur

Hobbit-The Battle of the Five Armies

“During the Third Age Galadriel became filled with foreboding, and with Celeborn she journeyed to Lorien and stayed there long with Amroth, being especially concerned to learn all the news and rumors of the growing shadow in Mirkwood and the dark stronghold in Dol Guldur.” (J.R.R. Tolkien’s Unfinished Tales, 256)

The Hobbit-The Battle of the Five Armies

"Anon Lana, “Naked Hill” was the highest point in the highland at the south-west corner of Greenwood, and was so called because no trees grew on its summit. In later days it was Dol Guldur, the first stronghold of Sauron after his awakening.” (J.R.R. Tolkien’s Unfinished Tales, 292)

Dol Guldur- “Hill of Sorcery” was the treeless height in the south-west of Mirkwood, where the Necromancer dwelt until he was finely revealed as Sauron (The Dark Power). He would eventually be banished by Galadriel and the other members of the White Council.
