Jules Petrequin Mansion

Built in 1912 at 600 Market street by Jules Petrequin, part owner and general manager of Western Lime Works, said to be built for his crippled son, Nicholas. He was nursed by Viola Oberle, and when Jules died, she and her husband were invited to move into the house. The Knights of Columbus purchased the stately manor in 1959 and it serves as the K of C Hall today.
