Participants spent the night at the site in sleeping bags and blankets in the cold, waiting for the ceremony to begin while watching documentaries and interviews about the Battle of Çanakkale during World War I.
In the program that started at dawn, Australian Veterans Affairs Minister Matt Keogh and New Zealand Defense Minister Andrew Little delivered speeches on the significance of the day.
The letter of Mustafa Kemal Atatürk, founder of the Turkish Republic, to the families of foreign soldiers who lost their lives in the Battle of Çanakkale was also read.
The unsuccessful eight-month campaign saw more than 44,000 British, Irish, French, Australian, New Zealand, Indian and Canadian troops, as well as nearly 87,000 Ottoman soldiers, killed.
The day is also commemorated in Australia and New Zealand as ANZAC Day and Gallipoli is seen as one of the defining events that ushered both countries towards nationhood.
The battle also forged links between Türkiye, which emerged as a modern state shortly after the war, and the ANZAC countries.
