This is a tough one for any tallented BAT'ers out there: Philadelphia City Hall http://www.princeton.edu/~yisun/album_files/PH_City.jpg'> It was constructed from 1871 until 1901. It is the worlds tallest masonry building at 548', topped of with a 37' statue of William Penn. It is an absolutley beautiful building, and It would be greatly appreciated if anyone could do it
