WOW Zone:Scholomance  

From Blizzard's Official World Dungeons site:

...The Scholomance is housed within a series of crypts that lie beneath the ruined keep of Caer Darrow. Once owned by the noble Barov family, Caer Darrow fell into ruin following the Second War. As the wizard Kel'thuzad enlisted followers for his Cult of the Damned, he would often promise immortality in exchange for serving the Lich King. The Barov family fell to Kel'thuzad's charismatic influence and donated the keep and its crypts to the Scourge. The cultists then killed the Barovs and turned the ancient crypts into a school for necromancy known as the Scholomance. Though Kel'thuzad no longer resides in the crypts, devoted cultists and instructors still remain. The powerful lich, Ras Frostwhisper, rules over the site and guards it in the Scourge's name — while the mortal necromancer, Darkmaster Gandling, serves as the school's insidious headmaster...

Scholomance is found buried in the ruins of the once magnificent House of Barov, overlooking the undead-infested ruins of Caer Darrow. The dungeon is designed for a party of 5 players, between levels 56 through 6, very similar to the dungeon of Stratholme. In addition, either the Skeleton Key or a rogue with at least 280 lockpicking is required to enter.
