I have no idea, but it's more than likely scrapped or sold - there was a big Trek clearout a while back...
This german collector bought a huge amount of material in the big sale a few years back. He has a classic bridge set in his collection - unfortunately his website does not say where it's from. http://www.filmwelt-collection.com/
Not really, because keeping sets in storage costs money and with no future shows or movies planned that would use those sets, there truly was no sense in paying to keep them. It's standard procedure when a TV series ends.
Usually sets are demolished immediately after production ends. That's not just for Trek, but for TV shows in general.
John Eaves seems to agree with you: http://johneaves.wordpress.com/2009/04/16/the-fall-of-rome/ "To end the 40th with a bang, a demolition derby would be the last hooray and what was left was bulldozed. It is a sad time when history has no meaning and is thrown away."
I have a question. Why is this discussion taking place in the Enterprise forum? The Defiant was on DS9.
The set was struck and actually left OUTSIDE, exposed to the elements during a rainy winter. I didn't see the effects of the rain myself, but was told it was a sad sight. I was given a copy of the blueprints by folks in the production; the blueprints are what really matter for recreating that particular incarnation of the TOS set.
Yay, yet another person under the mistaken impression that Moonves hates Star Trek. He hates shows that are expensive to produce and only have a minimal viewing audience. If Star Trek was cheap to make and had the same audience that all those reality shows have, he'd green-light a new Trek show tomorrow. How is it wrong to get rid of a set from a cancelled show? Friends was a hugely popular show, and yet they didn't scavenge the sets to sell things to the fans.

"Paramount is planning something huge and keeping us out of the loop" Which is exactly what happened. Ah, foreshadowing...
Thank you for the confirmation, sir, regrettable though the details must be. The Defiant was marvelous to see again on Enterprise--such a beautifully detailed recreation. We always enjoy you dropping by.
If you take a tour of the Warner Brothers Studio, they take you to the coffee shop set... it's been rebuilt just off the prop building. They take all the tours there... you can even take a picture of yourself sitting on the couch.
