Article Photos: NY's largest cemetery celebrates 175th anniversary 1/12

This May 2, 2013 photo shows the the burial site of DeWitt Clinton at Brooklyn's Green-Wood Cemetery in New York. The 478-acre site is celebrating its 175th anniversary this year and a special exhibition on Green-Wood is opening at the City Museum of New York.  While it cannot replace a visit to the cemetery grounds, it provides a historical context for one of only four U.S. cemeteries to be granted National Historic Landmark status.(AP Photo/Mary Altaffer)
