More than 1,000 enclosures were removed from 1950 to 1961 , the same year that work on a new crematorium began . The columbarium was expanded from 1975 to 1977 . However , through the 1970s , vandalism was common at Green-Wood Cemetery . The cemetery was also affected by labor strikes among the gravediggers in 1966 , 1973 , and 1982 . The cemetery also continued to add new structures : the Garden Mausoleum and Community Mausoleum were finished in the late 1980s , and the Hillside Mausoleum was expanded . In addition , in 1994 , the north gate was restored and new offices were built . This was followed by the restoration of the chapel in the late 1990s , and it reopened in 2000 after having been closed for four decades . In 1999 , The Green-Wood Historic Fund , a 501 ( c ) ( 3 ) not-for-profit institution , was created to continue preservation , beautification , educational programs and community outreach as the current " working cemetery " evolves into a Brooklyn cultural institution . The Historic Fund 's Civil War Project , an effort to identify and remember Civil War veterans buried at Green-Wood , was created following the rededication ceremony of the Civil War Soldiers ' Monument . These early graves had either sunk into the soil , been damaged , or had their markers erased before the monument was restored between 2000 and 2002 . Further , construction of the last phase of the Hillside Mausoleum began in 2001 , and the same year 50 victims of the September 11 attacks were buried there . On August 21 , 2012 , in one of the worst cases of vandalism encountered in Green-Wood , about 50 monuments and memorials were damaged . On October 13 , 2012 , another '' Angel of Music '' was installed to replace the one vandalized in 1959 , this one made by sculptors Giancarlo Biagi and Jill Burkee , was unveiled to memorialize Louis Moreau Gottschalk . Two weeks later , Hurricane Sandy toppled or damaged at least 292 of the mature trees , 210 gravestones , and 2 mausoleums in the cemetery . The damage was estimated at $ 500,000 . In December 2012 the statue '' The Triumph of Civic Virtue '' by Frederick MacMonnies was moved to Green-Wood . In August 2013 , in partnership with the Connecticut Society of the Cincinnati , signage in the Battle Hill area of the cemetery was updated to reflect new research on Battle Hill 's importance in the Battle of Brooklyn
