The pictures show the memorial ground. The cemetery is located down a path on the West side of the original Fletcher mansion (college President's residence). Between the two ponds is a path that crosses to the other side (near the first pond). A small sign marks that path. When you go another 200 feet you see what the other pictures listed that show, the Cemetery. This is only a Slave Cemetery. The Fletcher family and various graduates of the Sweet Briar College are interned on an adjacent hill in a more traditional cemetery with more expensive memorial stones.
One picture describes the site, one shows an overview, one shows a map of the interned by number, and a plaque naming the site.
The Plaque says:
"Sweet Briar Plantation Burial Grounds
Sacred Resting Place of Unknown
Founders Who Labored to Build What
Has Become Sweet Briar College.
We Are in Their Debt."
Sweet Briar College will be closing in August 2015.

The description says:
"Enslaved African Americans who lived and worked on the Sweet Briar plantation during the antebellum period buried their dead in this area. Many of the sixty (at least this) burial sites discovered here are marked by field stones. Slaves in Virginia were prevented by law from learning to read and write; therefore, it is not surprising that none of the stones in this cemetery contain inscriptions.
In 2003 a memorial was erected at this site (the plaque and description plate) to honor the African Americans who labored on the original plantation and, as a result, helped create the foundation for the college now known as Sweet Briar. Descendants of this community, the Fletcher family, held a reunion at Sweet Briar in 2008 and reconsecrated the ground in a ceremony honoring the lives, legacy, and faith of their ancestors."

The map picture shows small clusters of interned people. It is believed that they are family members. No names are known, although Martha Penn Taylor and her sister Mary were slaves. Martha may not be buried here as she was emancipated in 1865 and had moved and worked for Daisy Williams (the Fletchers only daughter) as a nursemaid.
