English: Withernsea Lighthouse coat of arms, Withernsea, East Riding of Yorkshire, England.
This inland lighthouse was formerly owned and run by Trinity House of London. It ceased operation on 1 July 1976 and is now used as a museum. The lighthouse is nearly a quarter of a mile from the sea front. At the time it was built, there was nothing between it and the sea but sand dunes, and fear of coastal erosion led to it being positioned well back.

The safety of shipping and the well being of seafarers have been the prime concerns of Trinity House since it was granted a Royal Charter by Henry VIII in 1514.
Trinity House is the General Lighthouse Authority (GLA) for England, Wales, the Channel Islands and Gibraltar. Its remit is to provide Aids to Navigation to assist the safe passage of vessels through some of the busiest sea-lanes in the world.
It was granted its Coat of Arms in 1573:
The grant of Arms was made issued by Gilbert Dethicke, Garter King at Arms:
“… I, the said Garter Principall King of Armes, have assigned, gyyen, and graunted unto their Corporacon aforsaid such Armes as they may lawfully bear in those necessary affaires of theirs as shall seme best: that is to say – argent, a plain cros geules, betwene four ships sable, the fore and top-sayles up, vnde underneath on a wreath of theyr colers, a demi-lion rampant, gardat, and crouned with a croune imperiall or, in his right pawe an armyng swoord argent, hylt and pomell or, langued and armed azure, mantled argent, doobled geules…”
In modern terms:
Arms: Argent, a plain cross gules, between four ships sable, the fore and topsails up.
Crest: A demi-lion rampant, guardant, and regally crowned or, in his dexter paw a sword erect argent, hilted and pomelled of the first. The mantling is argent doubled gules, and the motto of the Corporation, Trinitas in Unitate.
