Gerrans parish church (dedicated to St Gerent or Gerendus) was built in the 13th century and enlarged in the 15th century when the south and aisle and the tower topped with a spire were added.
However, in 1849 everything except the tower was rebuilt (by William White of Truro) though this was done as closely as possible to the original church.
The two-stage tower is buttressed, battlemented, and topped by a spire.

There is a fine Cornish cross in the churchyard.
According to Andrew Langdon (1994) this cross was not originally a churchyard cross but a wayside cross.
No other ancient stone cross exists in the Roseland Peninsula; however a cross called Penpirthe Cross is shown on the parish terrier of 1613 as standing on the boundary of the parishes of Gerrans and Philleigh.

The manor of Tregear belonged to the Bishops of Exeter in mediaeval times and Gerent may have had a castle (Dingerein or Dinurrin) here.
At the time of Domesday Book (1086) the manor was recorded as having 12 hides of land and land for 60 ploughs.
The lord (the Bishop of Exeter)  held half a hide of land with 2 ploughs and 6 serfs, and 18 villeins and 12 smallholders had the rest of the land with 16 ploughs.
There was a quarter of a square league of pasture and half a square league of woodland.
Though the value had formerly been only £5 sterling the manor was then worth £8.
The manor of Tregear (or Tregaire) was one of the Cornish manors of the Bishops of Exeter; it covered much of the Roseland peninsula.

A small museum, the Gerrans Parish Heritage Centre, is located in the village.
