The date of the building of Polperro's older quay is uncertain but Jonathan Couch (writing in the mid-19th century) considered that it is either the one mentioned by John Leland or one built upon the same site. It was probably built under the patronage of the lord of the manor of Raphael who owned the harbour and its rights. Polperro's newer quay, also of unknown antiquity, is sited almost on an east-west alignment a little further out to sea. It was built before 1774 when it suffered much damage in a storm, following which Thomas Long, of Penheale and lord of the manors of Raphael and Lansallos, paid for its repair.
