St Bueno Hotel, Clynnog Fawr, was a large coaching hostelry built to serve travellers between Caernarfon and Pwllheli and the west end of the Lleyn peninsula. It has been variously known as The New Inn, c.1840, The Newborough Arms, and until recently the St Beuno Inn. Although it probably has 17th century origins, the present building is largely of the late 18th century, but has the external character of its early 19th century remodelling. It was extended to the south by a large 2-storey wing in 1912.

It is a 2-storey building, constructed of stone rubble, part roughcasted, and whitewashed, with slate roofs with wide boarded eaves. The building is dominated by a wide-spreading gable facing the road, with deep eaves on purlin brackets, the apex hipped for a central stack, and more similar but smaller gables to the side. It has a small pedimented porch suppported by 4 slim columns.
