I agree the history makes them Interesting; the roles played in protecting people out at sea and the life of the keeper; often isolated existence.
I also tbink they can be such u usual architectural structures. Many round ones; so a challenge to furnish and I imagine just one room before floor and I admire the staircase.
In pictures can look amazing as have sea and dramatic cliffs around them due to their original function.Source: What Makes a Lighthouse So Appealing?
