In 1800, there was no significant coastal settlement. The present town was planned and developed from 1805 by the Rev. Alban Thomas Jones Gwynne. He built a harbour which operated as a port and supported a shipbuilding industry in the 19th century. A group of workmen's houses and a school were built on the harbour's north side, but these were reclaimed by the sea. Steam ships continued to visit the harbour until the 1920s but, in later years, it evolved into a small half-tide harbour for recreational craft. The estuary is also crossed by a wooden pedestrian bridge.
