Welby's Grade I listed Anglican parish church is dedicated to St Bartholomew the Apostle. The church originates from the 13th century and is mainly Early English, but with a Perpendicular clerestory and porch. In 1873 the north aisle was extended and the chancel rebuilt by J. H. Hakewill, who matched the Early English style. Within the porch is a 14th-century stone tomb cover with relief depictions of a woman's head and shoulders, within a quatrefoil recess, along with a shrouded baby. It was originally sited in the graveyard.
