Beginnings of the church of St. Michael in Llanfihangel Nant Brân are not known. The church tower was built in the 16th century, at the nave, which was completely rebuilt in 1882.
The original church probably consisted of a rectangular nave and a not externally separated chancel, which formed the entirety. The window on the eastern side was two-light, in the style of perpendicular gothic, while the window on the south side of the chancel was two-light in the form of a trefoil. The entrance led through a simple ogival portal and a porch on the south side. The tower was added in the 16th century and it is massive, low, with a square turret to the staircase from the south-east side. The tower is opened towards the nave with a pointed arch arcade.
