The village is 5 miles (8 km) east of Combe Martin, at an elevation of 180 metres, separated from the coast by high cliffs.
James Hannington, a future saint and a martyr, took charge of the parish church in 1873.
In 1973 a small ecologically-themed free rock festival was held on a clifftop site near Trentishoe, titled the Trentishoe Whole Earth Fayre (possibly following a minuscule 1972 festival of which records are sparse).
The 'International Times', in 1973, noted "The Trentishoe bash, kicking off on July 9th and running for a couple of weeks, looks like kindling a similar flame to that ignited by the Glastonbury Fayre".
[3] The organisers of the 1973 event were Greg Haynes, Mike Tanner, Dave Mackay and Norman with music arranged by Greasy Truckers and Bath Arts Workshop.
