The parish church in Llangwm was mentioned for the first time in historical documents in 1128. In the thirteenth century, the church had to undergo a significant reconstruction, because the oldest fragments of the current building date back to this century. It was also enlarged in the fifteenth century, when the church tower was added. In the nineteenth century, the temple was in ruin, which is why in 1863 a thorough Victorian renovation combined with reconstruction was carried out.
The church is a rather unusual building consisting of a longitudinal nave on a rectangular plan and a short rectangular chancel. A fifteenth-century tower with a polygonal south-west turret that houses a staircase is attached to its northern wall. The whole is topped with a prominent parapet with decorative crenelage. The porch on the south side of the nave and most of the windows come from the nineteenth century, but they are distinguished by very high quality. Inside, the most valuable element is a fifteenth-century, oak rood screen, separating the nave from the presbytery.
