A few days ago I posted about a visit to St. David's Lighthouse. I talked about another lighthouse to the south and west of St. David's that we had seen the as we approached Bermuda in the dark. That lighthouse was the Gibbs Hill Lighthouse. The light from the Gibbs Hill Lighthouse is visible for 30-40 miles. Today we went to visit this lighthouse. We climbed 185 stairs to get to the top of the 117 ft lighthouse. It sits on a hill that is 245 ft above sea level making the light 362 feet above sea level. The light source is a 1000 watt electric bulb. It is the worlds oldest cast-iron construction lighthouse, the pieces were all made in England and shipped to Bermuda where is was assembled in 1844-1845. It was first lit in 1846.
One of the pictures in this series is up at the lightbulb inside the concentric lens structure. I found it very interesting that the whole lens structure rotates around the bulb. For some reason I figured the bulb would be the thing that rotated or blinked on and off.
