You wouldn't believe
Pretty as they are, the lakes were built for a purpose. In winters past, their frozen water would be carried to specially built ice houses: pits made from brick or stone, deep underground. When full they would be sealed making ice available throughout the summer months. Of course, this was only available for the wealthiest few and it was in the kitchens of the gentry that ice cream recipes were devised - a luxury unimagineable to the poor cottagers. They often struggled to feed themselves the most basic diet.
