413 Petersburg Discover a true piece of Texas history with this rare Pioneer Castroville Home - the Mangold-Holzhaus House at 413 Petersburg. One of Castroville's earliest rock-and-plaster homes (pre-1855), this designated historic property is listed in the National Register of Historic Places and has been lovingly preserved for generations. Built as a classic Alsatian-style cottage with 18-inch thick walls, the home features original cypress beams and loft flooring, a heart-of-pine mantel adorned with distinctive stars, and a fascinating evolution from its original single-room layout with root cellar and sleeping loft. This is a home for the discerning buyer who appreciates Early Texas history, handcrafted details, and deep local provenance. It is decorated with original, and period pieces - all telling the story of Castroville's founding by Henri Castro and the settlers from Alsace-Lorraine who helped shape Texas.
