Palo Alto Plantation, Greek Revival plantation in Donaldsonville, United States

Palo Alto Plantation is a 1+1⁄2-story Anglo-Creole Louisiana plantation cottage decorated in the Greek Revival style, at the corner of LA-1 and LA-944 along Bayou Lafourche in Donaldsonville, Ascension Parish. It stands on brick piers with a twelve-foot-wide porch set under the roofline.

Built around 1847, the house passed from Mathias Rodriguez's succession to his daughter Rosalie and her husband Pierre Oscar Ayraud in 1852; its style suggests architect James Dakin. The Lemann family bought it in 1860 and still owned it in 2019. It joined the National Register of Historic Places on April 13, 1977.

Window panes here bear historical scratches with names and initials that families once used to test their diamond rings. These marked glass panels tell the story of visitors who passed through the house over time.

The property now operates as a bed and breakfast and event venue, so visiting often depends on prior booking or scheduled events. It helps to check ahead since access can vary based on current use.

French artist Marie Adrien Persac chose this Anglo-Creole plantation house as the subject for several paintings. This artistic documentation makes it an important subject in the region's art history.
