Geography and Location
Cork Harbour is situated in the northwest of Great Island, with the River Lee flowing through Cork city before passing through the upper harbour, also known as Lough Mahon.
The River Lee is the main tributary to the harbour, and its passage through the upper harbour is a notable feature of the area.

For navigation and conservation purposes, the harbour is often divided into two sections: Upper Cork Harbour, which follows the River Lee from Cork city to the towns of Passage West and Monkstown, and Lower Cork Harbour, which is separated from the upper harbour by Great Island.
The depth of the harbour varies, ranging from 4 fathoms to 14 fathoms.
You can find Cork Harbour at the coordinates 51°51’0"N, 8°16’0"W.
Economy and Activity
Cork Harbour is a significant industrial area in Ireland, with a long history of traditional industries like shipbuilding and steel-making. However, these have largely been replaced by newer industries, particularly in the pharmaceutical sector.
Several large international firms have set up operations in the harbour, including Pfizer, Novartis, GlaxoSmithKline, and Janssen Pharmaceutica. These companies are major employers in the region.
The main centres of the pharmaceutical industry in Cork Harbour are Little Island and Ringaskiddy, where over 100 other pharmaceutical firms also operate. Ireland's only oil refinery is located at Whitegate on the south-eastern shore.
The harbour has undergone significant changes in recent years, with some companies shedding jobs due to the post-2008 economic downturn. Notably, Pfizer announced the loss of 177 jobs in June 2012.

The Spit Bank
The Spit Bank is located to the north of Spike Island in Cork Harbour. It's a significant landmark in the area.
The Spit Bank Lighthouse is a navigational aid at the edge of the shipping channel. This makes it a crucial feature for sailors and boats navigating through the harbour.
