One of my favourite Street View pastimes is to wander the country lanes of north Devon. You can see old buildings and churches, often the inscriptions on the sides of buildings are visible, as are road signs, addresses and so on.
I took me a while, but I found Barland House in Dolton, Devon, on Google Street View. It's not that the image wasn't on Street View, but that I didn't know exactly where in Dolton Barland House was.
Here is a picture of Barland House taken circa 1900
Here is a Google Streetview picture of Barland House taken in the past few years, but from Rectory Rd.
If you click on the image you can see the sign on the fence in the lower right of the picture, it says "Barlands".
You can find Street View in Google Maps just look for the little gold coloured man in the upper left corner. Not every place has been "Street Viewed" by Google, but lots have. If you haven't tried Street View yet to see places your ancestors lived, you definitely should.
