Stanley Harbour is a large inlet on the east coast of East Falkland island. A strait called "the Narrows" leads into Port William.
It serves the town of the same name - Stanley - as a harbour. Stanley has sprawled along the south shore of the harbour, to gain shelter from the low hill of Stanley Common. As such this is the busiest waterway of the Falkland Islands and frequently visited by cruise ships, freighters and navy vessels, although this has lessened since the building of the two airports at RAF Mount Pleasant and Port Stanley Airport. It was formerly, and still is to some extent, a repair yard for vessels damaged in South Atlantic storms, or needing to restock.
The peninsula on which Canopus Hill, Port Stanley Airport and Gypsy Cove lie, together with a narrow spit of land known as Navy Point, effectively divides Port William from Stanley Harbour. This in turn creates a small bay in Stanley Harbour known as the Canache, which is bridged at one end.
Stanley Harbour is effectively the enlarged estuary of Moody Brook, which flows into it at the west end. It was enlarged as the result of glacial action.
Stanley Harbour has experienced a number of shipwrecks. The remains of the following can still be seen -
Stanley Harbour was originally known as Beau Port (French), later Port Jackson, and has sometimes been known as "Port Stanley".
In December 1914, the harbour was the base for a British Squadron lying in wait for the German Far East Squadron led by Adm. Graf von Spee. The first shots of the battle were fired by HMS Canopus, which had been grounded in Stanley Harbour as a guardship. Her gunfire was directed from a low hill on the peninsula, henceforth called Canopus Hill.
