Langthwaite is one of the few villages in
Arkengarthdale,
North Yorkshire, England. It is probably classed as the main settlement in the dale. It is one of the most northerly settlements in the whole of
Yorkshire Dales National Park. It is home to a
pub ('The Red Lion'), a shop and an unusual
commissioners' church of 1817, which was one of many then built with money provided by
Parliament in an attempt to counteract atheism and free thinking after the
French Revolution. Langthwaite is also home to a hexagonal powder house, built in 1807 to store
gunpowder used in the many mines dotted around the area.
