In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Llanddona like this:

Acres, 2,387; of which 470 are water. Real property, £1,644. Pop., 567. Houses, 134. The property is subdivided. The hill called Arthur's Round Table has traces of a Danish fort, and commands a very fine view. Another Danish fort is near the church; and an ancient camp is at Dinas-Silwy. Many of the inhabitants are employed in the herring fishery. The living is a p. curacy in the diocese of Bangor. Value, £87. Patron, Lord Boston. The church is dedicated to St. Dona; occupies the site of one built in 610; and was recently in disrepair. There is a Calvinistic Methodist chapel.
