You can find out more about our Listed Buildings Services here.

Church of St Adwen

This is a Church of England¬† Church in Advent, a village on the edge of Bodmin Moor. St Adwen is a Grade I listed parish church in Advent, Cornwall. The tower of this church is the only one in Cornwall with eight pinnacles. St Adwen, one of King Brychan of Brycheiniog’s daughters, is honoured at this church.

Church of St Nonna

Fans of Daphne Du Maurier will recognise this church in Altarnun. The church is mentioned in Jamaica Inn; it is the church where the evil vicar of Altarnun, Francis Davey, portrays himself as a wolf in a painting while his congregation has sheep heads. Creepy!

Antony House

A National Trust property near Antony. Another Daphne Du Maurier reference here, as a portrait hanging at the house is said to have inspired My Cousin Rachel.

Godolphin House

The Dukes of Leeds and the Earls of Godolphin used to live on the Estate. It is home to a Grade I listed Tudor/Stuart mansion with early formal gardens from about 1500, and Elizabethan stables from about 1600.

Pengersick Castle

Dupath Well

The spring at Dupath was once thought to cure whooping cough. It’s also thought that it was also sometimes used for baptisms. According to legend, two Saxons, Colan (Cornish for heart or courage) and Gottlieb, fought a duel for the hand of a lady in Dupath. However, the maiden remained unmarried: Colan was assassinated and Gottlieb was gravely wounded, though some accounts claim he died later of ‘impatience.’

(Cornish: Penn Dinas, meaning “headland fortress”) is an artillery fort built by Henry VIII between 1540 and 1542 in Falmouth, Cornwall, England.

Place House

Church of Saint Wenappa

This Quaker building is still used by the Society of Friends today.

Lanhydrock House

It includes the main reception rooms, nurseries, and some servants’ bedrooms, as well as the service rooms, nurseries, and some servants’ bedrooms. With over 200,000 visitors in 2004, it was one of the Trust’s 10 most visited paid-entry properties. Because of its old woodland and lichens, parts of the estate have been identified as an Important Plant Area by the organisation Plantlife. Lanhydrock was the setting for Trevor Nunn’s 1996 film adaptation of Twelfth Night, which starred Helena Bonham Carter as Olivia.
