"We often forget that architecture is much more than monuments."
"Architecture shapes most of the spaces we live in -- the little streets and alleys, the big squares and boulevards. They're defined by architecture the way a room is defined by its walls."
"A case in point is a charming brick-paved, tree-shaded, mid-block pedestrian alley in Cambridge, Massachusetts."
"Here, over a period of more than 30 years, a series of developers and architects, each working pretty much independently, added one little piece at a time until the Walk was complete. It was an amazing act of voluntary collaboration. Everyone saw the potential of the Walk and everyone made sure, as they built new buildings, to leave enough room for it."
