Rhosgoch (Welsh pronunciationⓘ; meaning: 'red moor') is a small village in the north of the island of Anglesey, Wales, about 3.5 miles (5.6 km) to the south-west of Amlwch.
A short distance to the west of the village is the small lake Llyn Hafodol and a mile to the south is Anglesey's largest body of water the reservoir Llyn Alaw (Water Lily Lake).
[1] The village once had a station on the Anglesey Central Railway.
[3] Also connected to the railway, was a short south-west facing spur that led to an oil terminal.
This was linked to a floating dock in the sea off of Amlwch, where super-tankers could dock in all tides and feed oil via Rhosgoch and a pipeline to Stanlow oil refinery.
