The installation instructions from https://pypi.python.org/pypi/Shapely say to download an executable installer from http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely but that gohlke web page only offers binaries for shapely for Python 3.5, none for 2.x.
Looks like the binaries for all Python versions are back up at Gohlke's web site, so this is now a non-issue.
