Awesome! Those are some big waves, and I'd be scared to be in those lighthouses.. How likely though is it for the lighthouse to actually break? I'm sure its based on the lighthouse and how well its built, but has a (modern) lighthouse ever been broken by a huge wave?
La Jument. I remember those pictures. Nice to know what its called.
I don't think it's a common thing, even with waves like that. I was reading up on some of this and the story of the Eddystone Lighthouse involves storm damage to some of the lighthouses that have stood there. (according to information, they're on #4, but this one has been up for more than a century. Although I've never seen a story about a modern, active lighthouse giving in to the waves, I don't think I can say it never happened.
