TV preview: Five things to watch on television this week

'16 Letters Sunday, RTÉ One, 7pm
The tumultuous events in the GPO 100 years ago are well documented but within its walls was a treasure trove of other stories, all told through the letters that passed through the building during that fateful year. Ryan Tubridy sifts through the historic correspondence in '16 Letters, a major documentary that gives an insight into the lives, thoughts and pre-occupations of ordinary people living through a time of rebellion.

The letters tell many stories, not all of them concerned with the Rising. There are tales of Irish men fighting in the first World War, a love story told in many letters written over six months, letters from a Capuchin monk who witnessed the Rising and its aftermath up close and a letter from a condemned man to his wife. All these stories are retold using dramatic recreations, and through interviews with the letter writers’ descendants – and all have a powerful immediacy not found in contemporary news reports of the time.

Sunday, RTÉ One, 9.30pm
Joe Duffy's award-winning, bestselling book The Children of the Rising told the forgotten stories of the 40 young people who were killed in the conflict.

Following on from last week's I Am Traveller, the documentary follows the lives of Ricardo, a member of the Roma community who dreams of becoming a garda, Elham, a young Muslim woman who has been assaulted for wearing a hijab and Nigerian-born Boni, who is torn between his parents' traditions and his new Irish identity.
