I believe the Beacon Hill neighborhood of Boston to be the most beautiful area of the city. My family loved visiting it when we lived in Boston but we always drove and I do not remember ever walking in the neighborhood though it is obvious it is best explored on foot.
We never knew the existence of this “museum” until we were walking past it on this trip. It was a cold and windy day and going into any building sounded like a great idea but this one turned out to be much more.
