About this Bed and Breakfast

Plas Tan Yr Allt is a unique country house, a Regency villa built by William Madocks and set in beautiful Welsh countryside just north of Porthmadog. The house has featured on Welsh television and has numerous fascinating historic and literary links. The poet Shelley lived here from 1812 to 1813 and completed his most celebrated of works Queen Mab "All things are recreated" in the house. Other notable residents have included the famous Portmerion founder and architect Sir Clough Williams-Ellis. One of the guest rooms is named after the architect's aunt Miss Mary Hilda Greaves.

The house is elevated on a hillside within 40 acres of ancient woodlands and has fabulous views across the Glaslyn Estuary, Ffestiniog Steam Railway and beyond towards Harlech Castle and the mountains.
