The Church of Saint David in Llywel is said to have been dedicated to three saints: David, Darn (Paternus), and Teilo; and known as Llantrisant. Its name was changed when it was granted to the Chapter of Saint David sometime between 1203 and 1229. The nave and chancel date to around 1480, but the tower is slightly earlier. Though the body of the church was restored by Sir George Gilbert Scott in 1869, what we see is almost entirely a product of the 15th century and earlier.
The church displays Perpendicular Gothic architecture. The grave of the writer and preacher David Owen (Brutus) is in the churchyard. As well holding a copy of the famous Llywel Stone, the Church holds the original Aberhydfer stone and old village stocks.
The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
