In 1884 - 1886, The present harbour area was taken into the care of The Port of Newlyn Harbour Commissioners' hands, and the base formed at the specific requirements of The Admiralty to provide the Admiralty Boat House. Mr T Bolitho provided the funds (as a loan) and drive for the Port to have a new harbour perimeter to 'replace' the ancient one which could barely include 40 boats. There has been a port here since well before 1450 perhaps as early as 1000, long before any appeared at Penzance, involved with the trade with the Mediterranean and France. This post is one of two set at the Pier base, which were erected to define the extent of the Harbour Commissioners' Boundaries. Though undated, it is from about 1886. It has been removed for safekeeping.
