Kilnsea is a village in the civil parish of Easington, in the East Riding of Yorkshire, England, in an area known as Holderness. It is situated approximately 2miles south of the village of Easington, on the north bank of the Humber Estuary.
In 1931 the parish had a population of 185.[1] On 1 April 1935 the parish was abolished and merged with Easington.[2] East of Kilnsea is the Grade II listed First World War concrete acoustic mirror used as an early warning device.
Kilnsea has one public house, the Crown and Anchor.
See main article: Church of St Helen, Kilnsea. In 1823 Kilnsea was a civil parish in the Wapentake and Liberty of Holderness. The parish church, dedicated to Saint Helen, was close to the cliff and in a "state of dilapidation" and "dangerous condition". Repairs were considered useless with the expectation that the sea, which had already swept away the graveyard, would take the church "in a short time". Population in 1823 was 196.[3]
The old St Helen's Church was lost to the sea in 1826, and was replaced by a new church in 1865, at a cost of £420, that incorporated some salvaged remains of the old building.[4] The church was listed as a Grade II building on 14 December 2018.
