In Southampton, Bermuda.
You can walk up to the top of Gibbs Hill Lighthouse and get some good looks at the island from on high. At about 120 feet tall, it’s one of just a few lighthouses in the world made of cast iron. That contributes to the “echo chamber” effect you feel when you walk up the steps to the observation deck.
Wouldn’t it be great if you had your own personal lighthouse, to guide you to safe harbor or warn you of treacherous conditions ahead? That would be really useful.
