At the very North end of Greystone is what's left of the mansion's swimming pool. It's been filled in with concrete so curious tourists like Teddy wouldn't fall into the water. Now it almost looks like a tennis court but it's actually used quite often for small weddings. In the second photo you can see the pool cabana--so luxurious! There are plenty of Italianesque details like the urn in the cutout that you can see in the last picture.
