Originally a chapel of ease to its mother church of St Stephen, St Thomas's church lies midway between St Stephen's and Launceston. The church is built predominantly in the Perpendicular style. The Romanesque features of the church are a large font, a tympanum and a crude figure panel.
The date of the foundation of the church is unknown because it is not mentioned in the Domesday Survey but Henderson states that it "witnessed both the rise and fall of its great neighbour", the Priory. The chapel may have thus pre-dated both the new Priory (1126) and Launceston Castle chapel (1136). The cemetery was consecrated by Bishop Grandisson on November 6, 1333 'in Prioratu de Launceston'. Sometime afterwards the church became parochial, which it remains, the parish being within the borough of Launceston.
