Well quite obviously Pelican Hill doesn't qualify, but who would have thought it would have been restored/rejuvenated on so soon?

My God, what a beautiful site for golf. Wish someone would have been able to build something worthy of that site.

Renaissance in Haverhill, MA was redesigned before it was open.  It's a Silva course now, I'm not sure if he was the architect of record from the beginning or not, but the course took a while to open because of all the rebuild work. (not to mention the club politic and financial issues)

Jeff, The only course that I know that fits your description of events is, The Dunes Golfer's Club, formerly The Dunes at Seville, in Brooksville Florida.

Art Hills built a good course on a sandy site, only to have the membership direct changes. Now, Mr. Hills is re-doing the course. What's odd is the re-opening date keeps getting pushed back and is still closed today.

 Ivanhoe CC outside Chicago might also qualify. But their pedigree is so screwed up, I can't keep it straight, who did what to whom. Originally a Dick Nugent, re-done, then re-re-done. Finally being put back to the original. I think(?)

Wade Hampton was tweaked by Fazio and all the bunkers and greens reworked 10 to 20 years after it opened?

The youngest course to be completely rebuilt has to be Mirabel in Arizona which wasn't even open when the owner tossed out Greg Norman to have Fazio redo it.

It's never happened.
No course has ever been returned to its' original state.

Mirabel came to mind for me too.

Angus Glen North in Canada was designed by Doug Carrick and Jay Moorish and overhauled by Davis Love within 4(?) years of opening.

Maybe Jeff had some insight in that GolfDigest just gave Gil Hanse best new remodel for 2007 for a 5 year old course at TPC Boston.

Ron Whittens article is below.

How old must a course be to qualify for Best New Remodel? Based on the selection of this year's Best New Private Remodel, TPC Boston in Norton, Mass., the answer is, "Not very old." A course need not even date from the 20th Century to be considered for Best New Remodel if its alterations involve sufficient strategic as well as cosmetic changes.

TPC Boston opened just five years ago. As the site of a PGA Tour event (the Deutsche Bank Championship) since 2003, it sported a solid routing and boldly contoured greens by Erik Larsen of Arnold Palmer Design Co. (After grumbling from a number of pros, some greens were toned down before the 2005 event.) Still, the rap against this TPC was that it looked more like a Florida course than a Massachusetts one, which might be expected when you give designers a parcel of Commonwealth laden with wetlands. The PGA Tour ultimately agreed, but to remedy that, it bypassed Palmer and hired architect Gil Hanse, an old school adherent who had done the impressive nearby Boston Golf Club. The goal of Hanse, assisted by associate Jim Wagner and PGA Tour consultant Brad Faxon, was to make this toddler look and play more like an 80-year-old New Englander.

Lots of interesting responses, but it sounds like what I am hoping might happen has no precedent. Some very young courses have been plowed under or dramatically altered, but I don't think anybody has named a course which was built, got altered in its first 10-15 years of existence, and then got put back to its original state. Truly restored..."oops, we really shouldn't have changed this, should we".

Jeff:

High Pointe and Apache Stronghold will be candidates someday.  However, they weren't really altered after 10-15 years, just neglected.

If a course is really altered early on, it isn't going to be restored until there is a change of ownership.  Nobody is going to admit error in that manner.

Pinehurst No. 7 opened in 1986 and went under the knife in 2002.

lest we also add Dismal River and TPC Sawgrass to this list???

Didn't Rustic Canyon survive a flood or a fire or something too?

Does that count?

Muirhead returned to soften the edges, so to speak, of Stone Harbor, correct gentlemen?

In lieu of understanding the question correctly, I propose the following courses OUGHT to do so.

Return Ojai, Riviera & Bel Air to their original G.C. Thomas state.

Take the Fazio out of Oak Hill and Inverness.

Demolish a hotel and bring back Lido!!!

I once read Sharp Park was a fabulous course.....
