This photo was taken a block or so off Spruce Street in Philadelphia's Society Hill. (thanks twoeightnine) Many of the townhomes in this district date back to the 19th and late 18th century. But this photo is a good example of how high density real estate is slowly chaniging the face of the city and the character of historic neighborhoods.
I've nothing against high-rises. In fact, I'm trying to talk my wife from our suburban home into one of the many high-rises sprouting up in Center City. It's just interesting to see these architectural styles juxtaposed.
