Where Am I and Whaddaya Know?

Just one person had a crack at last week's quiz, but that was all it took to get it right. It was a picture of Jane DeWolf's personal dollhouse, which is inside H.L. Reynold's Store in Lyme, a store that has been run by her family since it first opened in 1859. The business that she runs within the store is Jane's Dollhouses and Miniatures. 

Congratulations, Gloria, for being the first with the answer!

Now on to this week: Where Am I? 

And the question is: Which governmental agency operates next door to this location and what does it do?
