About Tŷ Siamas
Welsh folk music nearly disappeared. Through the 19th century, Nonconformist chapel culture — powerful, morally serious, and suspicious of dancing and secular music — suppressed much of the tradition that had been played at fairs, weddings, and gatherings for centuries. The harp survived, the choral tradition thrived, but the dance music and the fiddle tunes that had accompanied noson lawen evenings across Wales faded nearly to silence.
Tŷ Siamas in Dolgellau is part of the recovery — Wales's national centre for folk music and dance, celebrating a tradition that is flourishing again among a new generation of Welsh musicians, singers, and dancers. The free exhibition traces the history of Welsh folk music from the triple harp and the crwth to the contemporary revival; the concert programme brings that music alive in the intimate space of a former courthouse in the dark granite heart of one of north Wales's finest towns.

Frequently asked questions
Tŷ Siamas (the name translates as "James's House", referring to a historic local figure) is Wales's national centre for folk music and dance, based in a restored 19th-century courthouse building in the centre of Dolgellau. It was established to celebrate, preserve, and develop the living tradition of Welsh folk music — the music played at weddings, fairs, and gatherings across Wales for centuries, now experiencing a significant revival among younger Welsh musicians and dancers. The centre houses a permanent exhibition on Welsh folk music history and traditions, provides space for concerts and workshops, and serves as the base for the Sesiwn Fawr Dolgellau festival — one of the most important folk music events in Wales.
Welsh folk music traditions include: the harp (the national instrument of Wales, with a distinct playing tradition including the triple harp — the crwth — a bowed lyre that was the primary Welsh stringed instrument before the harp); fiddle (violin) traditions of north and south Wales; the penillion singing tradition (canu penillion), in which a singer improvises verse against a countermelody played on the harp; step dancing (dawns stepio) traditions specific to different regions of Wales; and the call-and-response traditions of Welsh choral singing that connect to the Nonconformist chapel culture of the 19th century. The exhibition at Tŷ Siamas traces these traditions from medieval sources through the 18th and 19th centuries (when much was nearly lost) to the 20th-century folk revival and the flourishing contemporary scene.
Sesiwn Fawr Dolgellau (the "Great Session") is one of Wales's most celebrated folk music festivals, held annually in Dolgellau — typically in July. Unlike large commercial music festivals, Sesiwn Fawr is rooted in the Welsh tradition of the noson lawen (merry evening) — informal music sessions in pubs, halls, and the streets of the town, with professional concerts as well as open sessions where anyone can join in. The festival draws musicians and singers from across Wales, Ireland, Brittany, and further afield. The Welsh language is central to the event. Tŷ Siamas serves as a hub for the festival and maintains the festival's heritage and archives. Visiting Dolgellau during Sesiwn Fawr (usually mid-July) transforms the quiet town into a vibrant musical gathering.
Yes — Tŷ Siamas runs a programme of concerts, ceilidhs (Welsh folk dances), workshops, and educational events throughout the year. Concert genres include traditional Welsh music, Celtic folk, and world music with connections to Welsh traditions. Workshop programmes cover Welsh harp, fiddle, dance, and singing — some aimed at beginners, others at experienced musicians. The programme changes seasonally; checking the Tŷ Siamas website before visiting is recommended to coincide with a concert or workshop. The evening concert programme in summer (June–September) is particularly strong, and the intimate performance space in the former courthouse is an excellent venue.
Tŷ Siamas is in the centre of Dolgellau, one of north Wales's finest small towns — a compact grid of dark granite streets with a notable architectural unity. The exhibition (free) takes 30–45 minutes and provides an excellent introduction to a Welsh cultural tradition that most visitors know little about. Combined with the town's cafes and the nearby Precipice Walk (a superb circular route above the town with views over the Mawddach Estuary) or the approach routes to Cadair Idris (3 miles south), Tŷ Siamas fits naturally into a full day based in Dolgellau. For visitors interested in Welsh language culture — as distinct from the more visible Welsh heritage of castles and railways — Tŷ Siamas is one of the best introductions available in north Wales.
