I'm a huge fan of these types of off-course curiosities and items that give a bit more character to the place.
You can see slivers of the academic buildings and dorms at Hotchkiss School's golf course (Raynor/Banks), our Jim Kennedy's domain. Looking back from the green of the par-five 7th:
Have a look at the barn behind the green of the short par-four 4th hole at Vista Links (Rick Jacobson):
The fence of which you can see a sliver in this picture encircles an old slave cemetery at Heritage Club (Dan Maples/Larry Young/Mike Strantz) in Pawleys Island:
Some may not, but I like the way these tee boxes on the par-three 17th hole at the Moorland (PB Dye) Course at Legends Resort were built:
A periscope by the tee of the second hole at Manchester Country Club (Bendelow/Emmet/Tillinghast)
I wish I had pictures of the barns at The Olde Farm (Weed), because those are awesome too.
