According to the Untermyer Gardens website:

The Temple of Love overlooks a magnificent view south along the Hudson River and the Palisades. Best viewed from below, it is a stupendous rocky fantasy capped with a round temple. It was the centerpiece of an extended rock garden and was flanked by terraced beds. The outcropping was an elaborate water feature, with water coursing all around it in various waterfalls and ponds. The Temple of Love was created by Carlo Davite, a Genoese stone mason who did work in the Paris Exposition, the St. Louis Exposition and at the Frick Museum.

Many of the rocks are hollowed out to form planters, and in Samuel Untermyer’s time, the entire creation was elaborately planted. There are three bridges in the rough stone and a small seating area with a rough hewn stone bench that can be reached through a rocky tunnel in the folly. An additional monolithic bridge crosses the pool at the base of the Temple of Love.

Looking up from the pool at the base.
