Durnholde

From WoW: IncGamers World of Warcraft Wiki

Durnholde was the chief operations centre for the Orcish internment camps which were set up following the Second War. Lord Blackmoore imprisoned Thrall at this fortress until the young Orc escaped. Later, with his people behind him, Thrall came back and razed Durnholde, which remains in ruins to this day.
