Old church sited on high spot from which both Mount’s Bay and St Ives Bay could be seen.  Shape of  churchyard suggest re-used Roman fort.  The church, which served as the parish church of Marazion until 1890s, burnt down on Good Friday 1853.  Rebuilt by William White of Truro, before he became famous as an architect.  During the 1920s the church was decorated by Newlyn artists, who were friends of the Anglo-Catholic vicar Bernard Walke.  Walke introduced statues and paintings from London antique shops or which he had inherited.  Church attacked and vandalised by Protestant law enforcers/iconoclasts in 1932.

1. Roman inscribed stone, possibly a boundary marker for a Roman-controlled tin mining area centred on Godolphin Hill.  A similar Roman stone is in Breage church.
2. Noti Noti inscribed memorial stone from Dark Age Cornwall.  Probably commemorates a local man - Not son of Not - earliest evidence of Christianity in the parish.
3. Tower and spire of late 14^th or early 15^th century date.  Only part of the church to survive the fire.  Whitewashed as a seamark.
4. Choir stalls painted by Newlyn school artists including the vicar’s wife Anne Walke, Harold Knight, Harold Harvey, Gladys Hynes, Norman and Alathea Garstin, Dod and Ernest Procter, the latter painting the pulpit panels with lives of Cornish saints.  Backs decorated by child prodigy artist Joan Manning Saunders.
5. Stone altars made by Newlyn mason and embellished by Ernest Procter and others. 
6. Paintings of St Joan (modelled on Dod Procter) and St Francis by Annie Walke and Roger Fry
7. One of best churchyards for elaborate and impressive tombs.  Tombs of the Garstins and Procters in new churchyard.
