The Church of St John the Baptist was founded by William FitzOsbern and given to an abbey in Normandy. The nave may be 11th century, as may be the Norman font. A north aisle was added at the end of the 12th century and a south aisle shortly afterwards. In the 14th century the chancel was rebuilt and the south porch was added. In the 15th century a chapel was added south of the chancel and east of the south aisle, and a four-centred arch was inserted in the south wall of the chancel to link it with the chapel. The north aisle was demolished, its arcade filled in and two-light Perpendicular Gothic windows inserted in each of the filled-in arches. The Perpendicular Gothic west tower was added towards the end of the 15th century. The square-headed windows in the south aisle were inserted in the 16th century and the spire was added to the tower probably early in the 17th century.
On the wall can be found a memorial portrait by John Flaxman, showing a woman holding pelicans in her hand in relief. The chancel has a modern reredos.
In front of the porch is a 19th-century Celtic cross by Joseph Clarke on the four steps of the old churchyard cross.
Near the Celtic cross a marble monument marks the grave of Edward Edwards, (1812–1886) the pioneer of the public library movement. The churchyard also contains four Commonwealth war graves of service personnel, three from World War I and one from World War II.
References: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.
