The Helles Memorial is a Commonwealth War Graves Commission war memorial near Sedd el Bahr, in Turkey, on the headland at the tip of the Gallipoli peninsula overlooking the Dardanelles. It includes an obelisk which is over 30 metres (98 ft) high. The memorial is the main Commonwealth battle memorial for the whole Gallipoli campaign, and also commemorates the 20,956 Commonwealth servicemen with no known grave who died in the campaign in 1915–1916, during the First World War. The United Kingdom and Indian forces named on the memorial died in operations throughout the peninsula, with main landings at Cape Helles and Suvla Bay, and the Australian and New Zealand Army Corps fought mainly at ANZAC Cove.
