The Lligwy chapel was erected in the 12th century. There are no known reasons for its creation, it is only supposed that it could have been a chapel of ease for the parish church, built for the congregation who were too far to the main church. It was a time when stone temples were just beginning to be built in north-west Wales, after the end of the Viking raids and attempts to take control of the island by the Normans.
In the fourteenth century, the chapel was rebuilt, when the upper parts of the walls were reconstructed and a small bellcote was installed. In the 16th century, a small annex was added to its southern part, the crypt of which was used to bury members of the local Pierce Lloyds family. For some time this family used the chapel as its private property. At the beginning of the 18th century, the building ceased to be used and began to fall into disrepair.
Initially, the chapel was a small, aisleless building on a rectangular plan without a chancel separated externally. It was topped with a gable roof. A simple entrance with a semicircular finial from the 12th century was placed on the south side, and small, single window openings were only in the eastern and southern walls. In the 16th century, a square extension was erected on the south side with a vaulted crypt placed under the stone floor.
