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:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
