La Grange was documented in the 1930s by the Historic American Buildings Survey (HABS) while the structure was undergoing extensive renovations and the exterior was re-photographed in 1961. La Grange was listed on the National Register of Historic Places in 1981.
The mansion has its share of ghost stories. One tells of piano music wafting from the empty house while it was under renovation in 2006 and neighbors came by to see how things were going. The thing is, there was no piano in the house, although there was one many years ago. When Benoni Harrison bequeathed items to a nephew, B. H. Jordan (1820-1891), including the piano in the parlor. A young girl is said to haunt one of the upstairs rooms.
La Grange Winery now contains nearly six acres of vineyards and a wine production facility. Tall boxwoods planted to replace shrubs that died, form an arch over the narrow pathway leading from the mansion to the production facility. A glass of red wine is placed on the mantel of the Tasting Room in the manor house daily, in case the ghost of Benoni Harrison is mulling about.
