Around this time, the large manor was divided into several smaller ones, of which North Lancing and South Lancing (as they became known) were the most important. Gradually, three settlements developed: North Lancing, closest to the Downs; South Lancing, near the coast; and the nearby Pende (now vanished), on the coast and briefly a successful port. No church existed in the area at that time, but one was established in North Lancing in the 12th century: a date of around 1120 has been suggested from analysis of surviving masonry at the ends of the chancel. In about 1180, an arched doorway, now forming part of the porch on the south side, was added.
