Adjacent to the site of now demolished Sully House, of the Sully estate, where Evan Thomas, the owner and agricultural improver lived in early C19: the division between the parishes of Sully and Lavernock, which includes Swanbridge, is between the two. Swanbridge had a slipway and there are records of shipping operating in the area from C16. Kelp was prepared by burning seaweed in pits - 1 ton of kelp from 20 tons of seaweed - and exported. Other exports were local plants, including sea-holly, sent to Bristol for medicines. Main exports in C17 and C18 were cheese, butter, wool, woollen goods and livestock. Coastal trade declined at end of C18 with closure of ferry between Sully and Uphill on the other side of the Bristol Channel.
