History
The north-south road running through Rhoshill formed part of a drovers' road moving local and Irish livestock as far away as England, a practice driven by demand for centuries. Even after the coming of the railways, stock would still have been moved from farms to Cilgerran or Crymychrailway stations by road. A pre-1850 parish map shows an inn at Rhos-hill, while later 19th centuryOrdnance Survey maps show that Rhoshill had two pubs, the Foundry Arms and the Bronwydd Arms, and a post office, all of which have since closed and become private dwellings. The Bronwydd Arms was subject to a receivership order in 1891.
