The Church of the Nativity, also known as the Ruffin Nichols Memorial African Methodist Episcopal Church.
11th & Mount Vernon Sts., Philadelphia.
Built by Napoleon LeBrun, 1844.
Demolition seems to have begun in 2012, a decision made based on economy. I stumbled upon the ruins mid-2013 and returned to find it flattened this month.

There’s a REALLY great organization, http://www.sacredplaces.org/, which works to help prevent beautiful buildings from this type of end by working with local communities and fostering a #sharingeconomy.
