I recently rewatched Paradise Syndrome, and I got to thinking about the large obelisk in that episode, the asteroid deflector. Where did the production crew come up with this thing? Was it an existing monument that was modified for use in the show?. Or did they build it just for a single episode?
With the pedestal it's fairly large.
Even if it's just painted plywood, constructing the structure would seem to be beyond the budget of the usually cash strapped 1960's show. Again to be used once.
Consider the money (and time) it cost just to build the shuttlecraft.
I've considered that it might have already existed, someone else built it for another purpose, and the Star Trek crew discovered it and pressed it into service.
Anyone know? Construction photos would be nice.
