Here you see a view of Rockport from above Beach Street looking south. In the foreground is Back Beach. Towards the middle of the image is Front Beach. Farther on is the town of Rockport, where you can see the steeple of the Congregational Church at just about the center of the image and the steeple of the Unitarian Church to the right of it. Towards the left is White Wharf.
I tried to find the spot from where this picture was taken, but was thwarted by the fact that I would have had to go onto private property.
As best as I can tell, it was taken from the area above Granite Street, roughly in the vicinity of where Granite and Beach intersect. In the elevated area above that, there are several rocky outcroppings where the photographer might have stood. Today, there are condominiums and private homes in that area.
This postcard was published by the Rockport Photo Bureau. Based on the markings and numbering on the reverse, I estimate it to be from around 1909.
