Two drawings show the dimensions of Fort Saint Ferdinand and its layout in relation to blocks and streets in 1819. On the back of one of the plans, the unidentified artist wrote that he found stumps of the colonial fortification on 1819 July 10, when the drainage canal for St. Ann, Orleans and Saint Peter Streets was being dug at the site of the Old Fort Saint Ferdinand. He made his discovery in the presence of Messrs. Peralta, Moore, E. Wiltz, Chauvin, and Moreau. A picket was found planted at the flanked angle of the bastion, and upon examination determined that the palisade had been composed of posts six inches by six inches.
