Great Island in the context of Fota House and Gardens

Rushbrooke is a populated area on the western side of Cobh on Great Island in Cork Harbour, Ireland. It is in the townland of Ringacoltig (Irish: Rinn an Chabaltaigh, meaning 'headland of the navy').

Fota (statutory spelling Foaty; Irish: Fóite) is an island in Cork Harbour, County Cork, Ireland, just north of the larger island of Great Island. It is the home of Fota Wildlife Park—the only such zoo or animal park (besides Dublin Zoo) in the country—, the historical Fota House and Gardens, and the Fota Island Golf Club and Resort. The island comprises two townlands, both called Foaty; one is located in the civil parish of Clonmel (the western half of Great Island) and the other in Carrigtohill civil parish (on the mainland).

Lough Mahon (Irish: Loch Machan) is a sea lough in the north-western part of Cork Harbour. Its area is about 12 km (5 sq mi).

Several Cork suburbs, such as Mahon, Douglas, Rochestown, Blackrock and Ballinlough as well as the town of Passage West are on its southern and western shores. To the north is Little Island and to the east Great Island.
