Sennen parish church is dedicated to St Sinninus (St Senán), a sixth century Irish saint, but has also been dedicated to St John the Baptist. There has been a church here since at least the 15th century. In 1327 and 1430 the patron of Sennen is described as a female saint Senana. However in later times it has been assumed that Senanus is the patron saint. The identification of this Cornish saint with St Senan of Scattery Island appears to have no foundation.
The present church has a chancel and nave, a south aisle and a north transept. A wall-painting depicting two round embattled towers was uncovered during restoration in 1867. There is also a headless alabaster figure representing the Virgin Mary in the transept. The church has a three-stage battlemented tower housing a ring of three bells.
There are five Cornish crosses in the parish. One is at Escalls and another at Sennen Green. Trevilley cross is one of only two crosses with a crucifixus figure on a cross carved onto the stone (there is a cross on the other side of the head). A cross on the churchyard wall came from a site near the Giant's Stone. A fine cross in the cemetery adjoining the churchyard was found in use as a footbridge near Trevear and moved to the churchyard in 1878. About 1890 it was moved to its present position.
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.
