The Nashville Zoo at Grassmere is a zoological garden and historic plantation farmhouse located southeast of Downtown Nashville. the zoo was middle Tennessee's top paid attraction and contained 6,230 individual animals, encompassing 339 species. The zoo's site is approximately in size. It is an accredited member of the Association of Zoos and Aquariums. History Dunn farm Nashville Zoo is located on property that was once a 300-acre slave holding farm owned by Michael and Elizabeth Dunn. The Dunn's original home, built in 1810 through slave labor, is still located on the property. Margaret and Elise Croft, the great-great granddaughters of Michael Dunn, the original owner, were the last of the family to live at this location. In 1989, archaeologists evaluating the property for its archaeological resources discovered an unmarked cemetery fairly close to Grassmere's entrance off of Nolensville Road.

In June 1996, then-Nashville Mayor Phil Bredesen proposed that either the Nashville Zoo be relocated from its Joelton location to Grassmere, or Grassmere be converted to a city park without animals. In October 1996, the Nashville City Council approved the terms of a lease agreement for Nashville Zoo to relocate to Grassmere. The Nashville Zoo remained open in Joelton. In May 1997, the Nashville Wildlife Park at Grassmere opened. Both the Zoo and the wildlife park remained open, but due to public confusion, the Zoo closed their Joelton site in October 1998 and focused
