In 1922 and 1923, Ireland was once more a battlefield, as the Civil War saw conflict break out all over the country. In this interactive series, photographer David Cleary returns to locations captured on film a century ago and takes new photographs showing how those settings have changed - or not.

This photo from the National Library of Ireland's collection shows an ambulance racing down O'Connell Street during the Battle of Dublin. While it may look like a Red Cross vehicle, according to a poster on the National Library's Flickr account, it's actually a private car belonging to a member of the Irish Automobile Association, who had been using their cars to transport first wounded soldiers returning from the front in WW1 and then fighters on both sides from the 1916 Rising on. While much of the street was destroyed in the Battle of Dublin, this section remains relatively unchanged.
