[2] Saint Cwyllog's Church at Llangwyllog is thought to date from around 1200, and is mentioned in the Norwich Taxation of 1254, although the earliest dateable features are a doorway and window from the 15th century.

The aftermath was reported by Charles Dickens in The Uncommercial Traveller, and the disaster led the Meteorological Office to introduce the first gale warnings.
