The Harp Inn was a coaching inn for the Crosskeys to Merthyr Tydfil stage coach during the 18th and 19thcentury. Prior to 1894 Parish business was often conducted here, and it was here that agents of Lord Senghenydd (by then the Marquis of Bute) collected 'chief rents' from his tenants.
The Davies family were landlords of the Inn for the best part of two hundred years, and a number of them were renowned harpists. When it became a requirement to give public houses a name, 'The Harp Inn' must have seemed most fitting.
