The bodies were cremated in crematories excavated in the rock, where the funeral pyre stood. The cemetery also has two outdoor mausoleums, and two crematories. Not to be left behind, crematories had an idea of making cremation beautiful. As embalming became more widely accepted and used, crematories lost their sanitary edge. Louisville Crematories and Cemetery Corporation owned the cemetery by the late 1980s. Louisville Crematories and Cemetery Corporation was dissolved, and its perpetual care fund lacks functional interest. Because of local ordinances, no additional crematories can be constructed in Westchester County. As a result, crematories are most often heated by burners fueled by natural gas. They started building crematories with stained-glass windows and marble floors with frescoed walls. In addition, filtration systems (baghouses) are being applied to crematories in many countries.
