Gibb's Hill Lighthouse, still operating, was designed in London and opened in 1846 and is the second cast-iron lighthouse ever built. It stands at 117 feet and 362 feet above sea level. It used to be lit by a concentrated burner of 4 large, circular wicks but today the beam from the 1,000-watt bulb signals ships at 40 miles off and planes 120 miles away. We climed the 185 spiral staircase and saw fantastic views of Bermuda from the top.
