It opened in 1934 and is believed to be the oldest sno-ball stand in the United States. It has been operated continuously by the Hansen family. After Hurricane Katrina and the subsequent death of founders Ernest and Mary Hansen, the shop closed for some time before being reopened by their granddaughter Ashley Hansen, in early summer of 2006. The shop is open annually from March to October.
The Ice Shaving Machine
Ernest Hansen built Hansen's ice-shaving machine himself, entitled the "Sno-Bliz" in the 1930s. It was the first ever block-ice shaver. The U.S. government granted the patent in 1950. 
The machine currently in use today was built by Ernest Hansen in 1939.
