The church of St. Bleddian in St Lythans was erected in the 12th century. In the sixteenth century, right next to the temple, a chantry chapel of the Buttos family was built. In 1861, the church was thoroughly renovated, and then the southern porch was erected.
The church consists of a rectangular nave and chancel, which is slightly narrower. On the west side, a four-sided tower is lightly embedded into the nave. Its upper window come from the period of the 19th century renovation. It is topped with a gable roof. Built on the south side of the church, the 16th-century chapel is a simple building on a rectangular plan.
