The lighthouse was built in an area at the opening of Jupiter Inlet that contains several shell middens. A shell midden is built up over hundreds of years by native peoples eating shellfish and then leaving the shells behind--basically a gigantic trash heap! Many in this area were excavated in the 1800s and early 1900s, so there is a very nice museum here with some of the artifacts found in the midden.
Some nice views from the top.
This is a first-order Fresnel lens, the largest and most powerful of the six classes of Fresnel lens. All were made in France. This is actually still a working light, so you cannot tour late in the afternoon. You also must be escorted to and from the lighthouse because the grounds are a Coast Guard station.
I did some exploring afterwards, driving my rental car along a beach drive with enormous homes. This below is a driveway! There are hundreds of no parking signs and no places to pull over, so it is obvious that they do not exactly welcome uninvited visitors to these places.
