Sadly, there ain’t much very left from the World’s Fair perspective - the Queens museum and Hall of Science are still pretty nice to visit. (We just hit the latter last fall.) The Unisphere (globe) is still there, cool in it’s own way and was refurbed in the mid 90’s - but not worth a trip on it’s own, IMHO.
Only other thing I can think of remaining off-hand are perhaps the most iconic since you see them when driving by on the LI Expressway: the ruins of the NY State Pavilion with the “Tent of Tomorrow” and 2 towers. (Probably recalled by many from the big scene in Men in Black.)
Now that I’ve talked it down, I suppose it is a pretty neat place from a nostalgic point of view.
I was born a month after this picture of the Tower of the Four Winds etc. was taken by my Dad, so I technically visited the fair - but mostly my view was obstructed by my mother’s maternity clothes.
While I don’t remember the Fair itself, I do have my own nostalgic perspective since I would sometimes visit in the later 60’s and early 70’s with my family to walk around, see the giant NYS map, or hit the one pavilions that had roller and ice skating. I also remember a 1st grade field trip to the Hall of Science right after they installed the NASA rockets. (Still have my pocket telescope souvenir!)
But in only a few years the decay of the building was obvious (as in most of NYC in the 70’s.) I remember teenagers standing around the dry fountains throwing chunks of cement at the Unisphere. Sad. After that, my 1982 prom was there at the elevated Terrace on the Park… then I hadn’t been back until a meeting I was part of at the Queens museum a couple of years ago.
I just took a look at the Google Map satellite view of the area - seems there’s more open there than I knew about, but is all tucked away in corners of the property. Guess I’ll have to investigate!
