The Hermitage Plantation was owned by Judge Pierre Adolphe Rost and was located at the center of the present Bonnet Carré Spillway. Judge Rost was married to Louise Odile Destrehan and also owned the former Destrehan Plantation. He was considered one of the most significant and wealthy plantation owners along the German Coast. The Hermitage was seized by the federal government after the Civil War and later returned to Judge Rost. George Frederick Kugler served as overseer for Judge Rost and later acquired Hermitage Plantation. The property was subsequently sold to the United States government to be used as the site for the spillway project. Lumber from demolition of the Hermitage Plantation was used to build houses on Apple Street in Norco. Another African American cemetery known as the Kugler Cemetery is located at this site. Legend lends an interesting story that George Kugler planted many of the oak trees along the River Road.
