Arguably Machynlleth's finest attraction, Moma Machynlleth (or the Tabernacle) is an art gallery featuring predominantly Welsh artists. It was converted in the mid-1980s from a Wesleyan chapel, and has since expanded to show art in seven exhibition spaces. Recent exhibitions at the Tabernacle include Romanticism in the Welsh Landscape, which displayed works by JMW Turner and Richard Wilson.
Although well worth a visit for the art alone, the Tabernacle is also home to the Machynlleth Festival, which takes place in the gallery's Auditorium in late August every year. The Festival's events include classical and jazz music concerts, poetry readings, and the Hallstatt Lecture focusing on aspects of Celtic culture. 2016 will mark 30 years since the Festival began.
