the Dept of Mysteries would be among the places that you can't
apparate to. However, Dumbledore had to put the DEs in a room with an anti-apparation jinx. That means that, if fact, you can disapparate from anywhere in the ministry.

Rachael's Reply: 
I agree that this is a likely possibility. The secrecy of the DOM would need to be protected by anti-apparation spells because I doubtthat the Ministry wouldeven allow the possibility that any old wizard could just apparate into it (think what theWeasley Twins would do if this were possible!) 

But, if only select wizards, "unspeakables", are allowed in, there should be no harm in allowing those authorizedwizards to disapparate when they are ready to leave.

Another thought is, maybe if a place is spelled againstapparation,it is automatically spelled against disapparation.However, apparation into the DOM I definitely think is a no, no.

Carol:
I definitely agree that you can't apparate or disapparate into the DoM itself. Bode, an "unspeakable" who works in the DoM, may well have apparated into the atrium (with a lot of other people), but he  rides the lift with Harry and Mr. Weasley. But I'm pretty sure that you can't apparate or disapparate *anywhere* in the MoM except the atrium, which is where everyone seems to enter and leave the building -- even LV and Dumbledore. If you can apparate inside the building, why have lifts on every floor? Even the memos take the lift. 

Kashelkar's reply:

It's possible that the only place where apparation/disapparation is possible within MoM is the atrium, however, in the scene, when Harry lifts the prophecy from the stand, the DEs start apparating all around him, how's this possible??? Doesn't this indicate that, it's possible to apparate inside the DoM, that too in the hall of prophecies??
