The canals were built to provide a more reliable source of water (important in the manufacture of 'de Nimes' cloth) than the Nemausus spring, and the gardens awere the first public ones in France (1750).
There are statues and fountains, winding paths and steps, little grottoes and nooks and crannies and pools (one absolutely full of tadpoles, which was quite a surprise in August!). The Temple of Diana at the bottom, and the Tour Magne at the top......nice to explore (to the raucous accompaniment of cicadas).
I spent a most enjoyable couple of hours there; I suggest you do the same.
