The last burial was in 1988. Included on the property as a contributing building is the Chapel of the Sisters, erected in 1857. Nicholas Ludlum was personally responsible for the construction of the “Chapel of the Sisters,” named so to honor his three daughters who died years before. In 2007, Queens Borough President Helen Marshall, in collaboration with preservation and community groups, celebrated the restoration of the Chapel of the Sisters, which took almost five years of fundraising by the Greater Jamaica Development Corporation and the New York Landmarks Committee. The main highlight within this project was to restore two rose windows decorating the north and south facades of the chapel. It was built as a Romanesque Revival building and measured approximately 40 by 40 feet and 25 feet high. The chapel was restored and in 2008 was re-dedicated as the Illinois Jacquet Performance Space, for the famous jazz saxophonist who lived in Addesleigh park, a jazz enclave in Jamaica. After upgrades that included a new heating plant, new plumbing and electrical systems, replacement wood windows and entry doors, new floors, and other stonework and design improvements, the chapel re-emerged as a concert/event space, which enabled the venue to be used for meetings and presentations. Before, during, after the 1980s, plans were made by various groups, committees, and individuals to properly maintain and preserve Prospect Cemetery. During this time, Prospect Cemetery had become a location of deterioration and vandalism beneath trash, poison ivy, and broken tombs. Amy Anderson, who took it upon herself to correct this stagnation/problem, stated “My ancestors came here and settled this country. I’m an American. I’m not going to let this go”. Not only was the cemetery found to be an official New York City landmark, but it was, according to Dr. Sherene Baugher, found to be the fourth-oldest surviving cemetery in the five boroughs. Furthermore, as part of the National Guard's Challenge Program for high school dropouts, 80 National Guard members and 14 students spend the day (Saturday, November 23, 1998) hacking, raking, and clearing the front half of the cemetery (near 159th Street and Liberty Avenue). Aside from restoring the dignity of the graves within Prospect Cemetery, the cleanup of about an acre of this property helped to destroy an environment conducive to drug trade and crime, as stated by event organizers.
