Well, Skara Brae, it's not that big a deal...just a little collection of old dwellings, recently exposed to the air...OK, well, they were exposed in the 19th century, and they're 5000 years old, and the conveniences these people fashioned for themselves are still there. The famed "stone dresser", a construction of rock slabs that form a free standing multi-shelved mantel, will probably give you pause to think. All told there are, what, 7 units, I think, all connected, and you can walk around above them. It's unfortunate you can't descend into them, although there is a mock unit which you can walk around.
The visitors center is pleasant, with a video presentation that's worth watching. There's also a 16th century manor on the same grounds, available for the same admission. When I was there, I was greeted by the current owner.
The site is right by the water (although it didn't use to be - changing landscape and all that) and is all and all a very pleasant and thought-provoking place to visit.
Something is not right. This message is just to keep things from messing up down the road
