Still visible at the opposite end of the garden from the cellar is the icehouse, an underground location that when filled with ice during the winter kept perishable foods at a temperature of 3-4 degrees Celsius.
Ice was collected from the lake and from the hemp pools across the complex. As late as 1920, it was loaded into the icehouse with shovels; wagons using “Decauville-like” tracks were later introduced.
The icehouse was constructed with specific architectural techniques (shaded location, north-facing opening, internal and external doors, floor with central drainage) that allowed the ice to last all year long.
