Strawbery Banke Museum in Portsmouth, NH, is a collection of a couple dozen historic structures dating from colonial times to the early 20th century. I heard about while working for the History Channel last year. Last week I visited.
The grassy area above is where the Puddle Dock was; this inlet connected the community to the nearby harbor.
I thought the best thing about the place was the attention to architectural detail and construction. One house is given over to an exhibit of the tools, techniques, and materials (wood, paint, wallpaper, etc.), which was fascinating.
Found this in the Victorian children's "fairy garden."
And this was hiding in one of the herb and flower gardens that dot the grounds. The place is, of course, a fantasy of American history, but then most things are.
