What structures were constructed to maintain stocks of harvested ice throughout the year?
Answer
Ice houses insulated with sawdust or straw
The management of natural ice stocks required significant infrastructure investment in the era preceding mechanical refrigeration. Large structures known as ice houses were constructed specifically for this purpose. To maximize the longevity of the harvested ice through warmer months, these houses were heavily insulated using bulk materials available at the time, such as sawdust or straw. These insulated storage facilities were crucial for maintaining a supply line, allowing items like dairy and fish to travel further than would otherwise be possible.
