“The abundance of wind on Anglesey provided a useful source of energy, and during the eighteenth and nineteenth century numerous windmills were built around the island. Almost 50 are known to have been built. Many of these are now in disrepair or have disappeared. However, one has found new life as a working mill, and others have been converted to dwellings and one has been reconstructed to house a mobile phone base station and mast. This talk will introduce you to the development of windmills and how they work and then discuss the history of several examples around the island.”
