It is a shame. We should really not lose anymore lighthouses.
All are historic structures in my opinion. We must find ways to work with private owners and even government bodies. And as much as I think all lighthouses should be open to the public at least several times a year, I would still volunteer time or donate money to save a private lighthouse knowing it would stay private (but standing and not in ruins). The owner could later change their mind.
And lets face it the owner has to die sometime and then the heirs may be more agreeable.
I hope to take action on my own words this year.
Take care,
