In the days before refrigeration, icehouses were designed to store ice in bulk for summertime use.
This book examines icehouses in Britain, where they were built in increasing numbers from the early seventeenth century, initially to provide chilled refreshment for the wealthy.
By the mid nineteenth century most country estates would have had one. Their design improved as scientific knowledge increased and, although the majority of icehouses remained plain, some exuberant structures were built.
