Cullerne Wharf of the Ordnance maps, or plain Cullerne as known to the countryside, lies two miles from the coast today; but it was once much nearer, and figures in history as a seaport of repute, having sent six ships to fight the Armada, and four to withstand the Dutch a century later. But in fulness of time the estuary of the Cull silted up, and a bar formed at the harbour mouth; so that sea-borne commerce was driven to seek other havens. Then the Cull narrowed its channel, and instead of spreading itself out prodigally as heretofore on this side or on that, shrunk to the limits of a well-ordered stream, and this none of the greatest. The burghers, seeing that their livelihood in the port was gone, reflected that they might yet save something by reclaiming the salt-marshes, and built a stone dyke to keep the sea from getting in, with a sluice in the midst of it to let the Cull out.
