Christian H. Heigold was a successful stonecutter who immigrated to Louisville from Germany in 1850, settling in a thriving neighborhood called The Point along the Ohio River just east of downtown.
Heigold quickly went about building his mansion, completing a majority of the house by 1853. While only a handful of his stone carvings have survived on the building’s façade, Heigold used his ample stonecutting skills to adorn his house with images of his family integrated into patriotic scenes, including busts of Presidents James Buchanan and George Washington. The façade is only a taste of his stonecutting skills; Heigold even cut the stone steps of the old Jefferson County Courthouse in Louisville.
