The idea is ingeniously simple: a museum, spread across two rooms of an elegant Georgian building, devoted to the history of Dublin in the 20th century, made up of memorabilia contributed by the general public. You don't need to know anything about Irish history or Dublin to appreciate it: visits are by guided tour and everyone is presented with a handsome booklet on the history of the city.

Since opening in 2011, the contributions have been impressive. Amid the nostalgic posters, time-worn bric-a-brac and wonderful photographs of personages and cityscapes of yesteryear are some extraordinary finds, including a lectern used by JFK on his 1963 visit to Ireland and an original copy of the fateful letter given to the Irish envoys to the treaty negotiations of 1921, whose contradictory instructions were at the heart of the split that resulted in the Civil War. Curator Sarah Costigan also runs a weekly tour of the exhibits focusing on women and their role in Irish history.
