Some facts:
The pier was built during the 18th and 19th centuries.
The first major alterations designed by John Smeaton, started
in 1770 and were completed by 1781. The extended pier reduced
the entry of sand into the harbour area and changed the
angle of incoming waves at the harbour entrance. The North
Pier was extended again between 1810 and 1816 on the advice
of Thomas Telford.
