Jupiter, FL

Jupiter is rich in history: the earliest known records of the Jupiter Inlet date as far back as 1565. Jupiter’s most identifiable landmark, Jupiter Inlet Lighthouse, was erected in the 1800s. The stately red brick lighthouse continues to stand, ranging 105 feet into the sky, atop a 46-foot hill on the north shore of the Jupiter Inlet. Stretching to the Atlantic Ocean, Jupiter features a delightful tropical climate and truly that “small town” appeal with big city benefits.
