The Trefriw Wells Spa was first discovered by Romans around 100-250 AD. In 1833 Lord Willoughby de Eresby built the Cyclopean Bath House for people visiting the spa. The Victorian pump room and bathhouse was built in 1873. The spa was restored and opened as a B&B in 1972. It is now owned by Nelsons natural health company. The building is a characteristic and highly stylised pseudo-vernacular style cottage of rough-dressed slate-stone blocks under a slate roof. It is one-and-a-half storeys with stepped gables, mullioned windows and porch.
