The Thompson Ice House is a working museum dedicated to the methods of  traditional ice harvesting in South Bristol, Maine. In 1974 the  Thompson Ice House was listed in the National Register of Historic  Places. It is believed to be the only commercial ice house on the Register to have stored naturally frozen ice harvested in the traditional way from a nearby pond.

Thompson Ice House Preservation  Corporation  oversees the operation of  the ice house. Two events are sponsored on an annual basis – the ice  harvest in February and the old-fashioned ice cream social in July.
