The National Wool Museum, located in Drefach Felindre, Llandysul, Carmarthenshire is part of Amgueddfa Cymru – National Museum Wales.Historically and into the 19th century, the production and processing of wool surpassed even coal as the most important of Wales' industries.
Both the mill and the village of Drefach Felindre are a national heritage site. Launched as the Museum of the Welsh Woollen Industry in 1976, it reopened in March 2004 as the National Wool Museum following a two year, £2 million refit partly funded by the Heritage Lottery Fund.
The restoration work includes a glass roofed courtyard and a new gallery which displays aspects of the National Flat Textile collection. As well as historic machinery, a raised walkway gives a view of textiles in production at Melin Teifi, the site's commercial woollen mill.In 2005 a Research and Collections Centre opened which includes a room dedicated to hands-on learning opportunities.
