Llanharry iron mine worked from the early 1900s but closed in 1976; its main
ore was
goethite, which was used at the local
ironworks. Since the closure of its mines and ironworks, Llanharry has been in economic decline, as are most
South Wales Valleys villages once dependent on heavy industry. Llanharry's proximity to the
M4 motorway in Wales has allowed its residents opportunities to commute to work more easily rather than seeking work locally. Llanharry contains a few small local amenities, such as a corner shop and a hairdressers. ==Education==
