Cuby Parish Church

The church of Cuby is dedicated to Saint Cuby, a Cornish saint: since the parish church of Tregony was lost to the River Fal around 1540, Cuby Parish Church has been in fact the parish church of Tregony also. The church was rebuilt in 1828 though some of the medieval masonry still exists on the north side and the tower (of two stages) is of the 14th century. In the south aisle is an inscribed stone of the 6th or 7th century (Nonnita Ercilini Rigati [...]tris Fili Ercilini). The church in Norman times belonged to the alien priory at Tregony but in 1278 ownership passed to Merton Priory in Surrey.
