Cemeteries were the first urban parks in the US in the early 19th century as church graveyards filled up. Mount Auburn Cemetery in Massachusetts set a trend of "rural cemeteries" on city outskirts that provided green space. However, as attitudes toward death changed and dedicated city parks emerged, cemeteries fell out of favor. Now, facing space constraints and fewer burials as cremation rises, cemeteries like Green-Wood in Brooklyn are reopening their gates and embracing public uses like yoga, movies, and music to stay relevant in their communities.
