Maine held its 9th annual "Open Lighthouse Day" on Saturday. People come from all over the country to tour as many lighthouses as they can on this day.

I see lighthouses as tiny enchanted castles, and I would love to visit them all.

It would be cool if New Hampshire had an "Open Lighthouse Day." If that were to happen, these are the four I'd like to visit.

Portsmouth Harbor Lighthouse

White Island Lighthouse, Isles of Shoals

Loon Island Lighthouse, Lake Sunapee

Herrick Cove Lighthouse, Lake Sunapee
