Oh wow, there’s something I really like about this piece of concept art! If it looks like a monument, it is of a fashion: it’s from the early days of what would eventually become Disney’s California Adventure. This sculptural spire would have been the centerpiece of what was then still being developed as “Westcot”, a west coast version of EPCOT. Interestingly, it’s the second version of the park’s centerpiece, the original being a large globe similar to EPCOT, albeit one planned to be enveloped in a second lattice work globe twice as big and embedded with a gazillion lights. That received some push back from the local community, and thus this spire was born, something to still maintain an impressive monumentality from within the park while reducing its visual impact from without.
There are other sketches that show the spire at the front of a landscape-like building, but while they’re neat I prefer this one above. It feels both more approachable and more impressive on its own, with the fountains and walkways and the stonehenge-like segmented slabs that surround it.
In the end, of course, it was never built, and the saga that leads us up to the park that is there today is a whole fascinating story of its own.
