Image 1: Chronology of Tennis Court with Notes.
1st image is a gif showing construction of a clay court.
I believe the Tennis court was in use for a while, then abandoned. The nets and fence would have been intentionally removed.
The traditional Green color of tennis courts comes from the type of clay used, Har-Tru is the name brand.
This sight has always remained centered on the original high point of the island, I believe this is ritually significant. It's proximity to the sundial and temple are important.
Current images show the area is grown over, but with tracks and circles dug into the dirt.
Those are not Epstein's tennis court, just a reference so we can see what a natural clay court looks like when neglected.
