Tŷ Mawr Wybrnant is a house located in the Wybrnant Valley, in the community of Bro Machno, near Betws-y-Coed in Conwy County Borough, North Wales. It was the birthplace of Bishop William Morgan, first translator of the whole Bible into Welsh. Restoration Tŷ Mawr Wybrnant is owned by the National Trust and has been restored to its probable 16th-century appearance. Despite its name (Tŷ Mawr, "Big House") it is very small by today's standards, but it houses some old furniture and a collection of Welsh Bibles, including William Morgan's Bible of 1588. There are also other Bibles in many other languages, donated by visitors to the house from around the world. Access The house is most easily reached from the village of Penmachno, 4 miles from Betws-y-coed, but can also be reached from the A470 between Betws-y-coed and Dolwyddelan. Ty Mawr Wybrnant closed to visitors in early 2020 due to the COVID-19 pandemic. The collection of Bibles was temporarily moved to a dedicated exhibition at Chirk Castle. Etymology The Afon Wybrnant is the stream near which the house is located, and its name is usually appended to the house's name to distinguish it from other Tŷ Mawrs. The origins of the name Wybrnant are not wholly known. Although nant denotes a small stream and wybr is an old word for sky or cloud, some would have it that the word is derived from a corruption of gwiber, meaning "adder" or "viper". According to legend, long ago a gwiber was a huge flying snake, and one lived in this valley.
