St Mary's Church, located in Carew, Pembrokeshire, Wales, stands as a significant historical and architectural monument. Nestled within a raised, rectilinear churchyard, the site reveals traces of its early medieval origins. The remnants of an ancient boundary are discernible as an earthwork in the north-west corner of the churchyard, hinting at the church's longstanding presence.
Documented references to the church date back to the mid-12th century, with a notable mention in the Taxatio of 1291, when it was assessed at £40. Originally dedicated to St John the Baptist, the church boasts a rich history intertwined with the local nobility and ecclesiastical patronage.
