icehouse
A building used for storing blocks of ice cut from lakes, ponds, and streams in winter; typically built mostly underground with masonry or timber walls lined with wood and with the hollow space filled with sawdust insulation; ice was shipped to southern U.S. from New England by sea pre-1799, then via the Mississippi River from Illinois and Wisconsin beginning in 1799.
