Here is the historical marker that gives a little background:

A few highlights:
The above sign informs us that this was the first in ground swimming pool in Florida and is fed by the aquifer.
One interesting feature of the estate house is that the columns around the wrap around porch are made of local woods and are not smoothed down, but rather are like natural cedar or palm trees with branches still attached - a hazard if you run into them, but very pretty to look at - just don't look too close or you might lose an eye!
On our way driving out we passed a group of four deer not 50 feet from the car but I had already put the camera away. I stopped to grab it and photograph them but another vehicle came by and the deer bounded away into the palmetto bushes and out of sight.
