Roche (pronounced Roach, Cornish: Tregarrek, meaning homestead of the rock) is a civil parish and village in mid-Cornwall, England, United Kingdom. The village gets its name from a granite outcrop east of the village. Roche is the Norman-French word for Rock. On the northern flank of the village is the 20-metre (66-foot) high Roche Rock, a large granite outcrop.
Roche Rock (Cornish: An Garrek) stands out as a rocky outcrop some 20 metres (66 ft) high on the northern flank of the St Austell granite with an approximate area of 600 metres (2,000 ft) x 300 metres (980 ft).) The rock is of interest to geologists as it is a fine example of quartz shorl; a fully tourmalinised granite, with black tourmaline crystals. The Rock itself lies approximately 500 metres (1,600 ft) north of the northern margin of the St Austell granite, which is the smallest of the five main apophyses of the Hercynian batholith of Southwest England. The presence of numerous pegmatites occurring as sheets and containing abundant miarolitic cavities carrying quartz, tourmaline, zinnwaldite, topaz. and a wide range of other phases, is why it is considered to have been close to the roof of the intrusion The site is considered to be of prime importance for future research and notification by English Nature as a geological SSSI occurred in 1991.
On top of Roche Rock is a ruined chapel (dedicated to St Michael). Roche Rock has many folk-lore tales associated with it, the two most famous being the legend of Jan Tregeagle, a seventeenth century magistrate, who after death found refuge in the chapel and the other being part of the Tristan and Iseult tale.
The church is dedicated to St Gomondas / Gonandus (Gonand or Goenandus): the tower is medieval but the rest of the church was rebuilt in 1822. There is a fine Norman font and a good churchyard cross. Gonandus may perhaps be identified with the Breton saint Conan, connected to three places in the diocese of Vannes.
Roche railway station is located approximately 1 mile north of Roche, at Victoria. Trains are operated by First Great Western. The station has a single track, with a marker board showing direction of travel either to Newquay or Par.
