The parish church is dedicated to St
Hermes and has a very unusual tower which was originally high and was built in the 14th/15th centuries. The upper part was brought down by explosives in the 1880s, but it was not properly capped until 1956 and now stands high. The church is in the Lann Pydar joint benefice with:
St Eval Church,
St Mawgan Church and
St Columba's Church, St Columb Major. The church was supported by the
Arundell family who lived at the manor of Trembleath as early as 1240. The English poet, Sir
John Betjeman mentioned the church in his poem "
Summoned by Bells" (1960), chapter VIII.
