Ten children from the inner-city St Audeon's National School came along to see Taoiseach Bertie Ahern.
The big round eyes of Andrei Zavastitaii (7), Megan Keogh (6) and Louise Naughton (6) gobbled him up. "You're all very quiet," he said to them. They were. They were squatting close to a human skeleton from the 12th century, which is part of the new Dublinia experience at Christ Church.
Ruth Delaney, of the Heritage Council, was fascinated by the maps. Ruair∅ Quinn, Labour Party leader, who assembled the key group to create Dublinia, was taken with the wall montage of Wood Quay press cuttings. Alan Montague, a Galloglass warrior dressed in a coat of mail with a mighty sword, was impressive too.
Eileen O'Mara Walsh, chairwoman of Dublinia and the Medieval Trust, and Suzanne Costello, its director, took us all down into narrow alleyways of the medieval city.
The exhibition project has been redeveloped, and it was opened officially this week. The Taoiseach waved goodbye to the waiting transition year students from Clonmel's Presentation Secondary School outside. Then the doors were opened and in they came.
