The pond in front of the temple is real and was still present during our visit.
Unfortunately an offshoot cult of mirror-Sulu fans have spray-painted "Oh my" on the temple's second level.

Everyone in our tour group patiently waits their turn for a photo op at the temple door.

Times are hard -- the temple gardener and lawn maintenance teams have been let go.
This is the pond in front on the temple. As I've gone through episodes picking out screen shots I am always amazed at how the choice of camera lens, filter and placement can increase the grandeur of a location or set.
The exit from the underground tunnels that lead from the outer perimeter to the temple is also located in this area.
