It's the same way all over Massachusetts. In the small towns where most of my relatives live, there are sections with buildings from the 1800's, mostly painted white.
The West Hanover three-bedroom two-story house my dad and his four brothers and a sister were born in at the turn of the century is still standing, and still owned and occupied by his sister and her family. She's almost as old as that tiny house and has lived there all her life. The house hasn't changed much in all those years.
Most of the houses in the surrounding streets are just as old and are also still occupied by members of the same original families. About the only thing that has changed is that they now have double-paned windows and better insulation in the walls. The kitchen wallpaper in my aunt's house is probably from the late 50's early 60's and she still gives it a good scrubbing every spring.
