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, from this period come the upper fragments of the walls. In the 16th century, a smaller room 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.
The chapel was a small, single-nave, aisleless building on a rectangular plan with no separate chancel. It was topped with a gable roof. A simple entrance portal from the 12th century is located on the south side. Small, single window openings were located only in the eastern and southern walls. In the 16th century, an annex with a vaulted crypt was erected on the southern side.
