The church in Chirk was built in the 12th century, probably on the site of an earlier temple dedicated to Saint Tysilio. The earliest written records about the church come from 1163. Around 1475, the original Norman structure was rebuilt in the English perpendicular gothic style. Renovations and restorations began to be carried out at the beginning of the 19th century. The church was partially rebuilt after being destroyed by a fire in 1853, further restoration work was carried out in 1877.
The original Norman church was a simple, orientated building on a rectangular plan, consisting of one nave without an externally separated chancel. In the second half of the fifteenth century, the northern aisle was added and the tower adjacent to it from the west. Then the windows were transformed into larger, gothic ones. The corbels of the northern nave roof also come from this period.
