Bryn Du Felin Isaf Windmill
Felin Isaf (also known as Melin Y Bont) on the Isle of Anglesey (Ynys Môn) in North Wales.
Anglesey, Bryn Du, Felin Isaf (Melin Y Bont) Windmill – as it was, with Bryn Du’s other Windmill – Felin Uchaf (Maelgwyn) – in the distance. 
Anglesey, Bryn Du, Melin-y-Bont Mill July 2009.
In my opinion the most sensibly designed of all the Windmills on Anglesey – built in 1825 – it could operate from the forces of both water and the wind. When the water levels were low on Anglesey it ran as a Windmill, when the weather was calm it operated as a Water Mill. I am not aware of any other on Anglesey that could boast the same, except possibly at Bodffordd, where there is a Windmill and a Water Mill, but built separately on the same site. That may well be the reason that this Windmill carried on working, possibly until the 1930s.
Now converted to a dwelling, and the water drained from the grounds.
