Dublin for The Three Generations: a Friday-to-Monday weekend

Free and on one lift-served floor: the Ardagh chalice, the bog bodies and the gold hoards, which work at eight and at eighty; closes at five.

Flat paths round the pond, benches every twenty metres, ducks to feed and the playground by the Leeson Street gate for the small ones.

A first-floor brasserie with a lift, long tables and a menu from roast chicken to a children's bowl of pasta, above the food hall.

DART to Dún Laoghaire, then seventy minutes across the bay past Dalkey Island and the Baily lighthouse, seats on deck and inside; runs spring to autumn.

Fish and chips, chowder and a children's plate at long wooden tables on the pier, with the trawlers unloading outside the window.

A level walk to the lighthouse with the seals in the harbour and benches along the wall, then the DART back from the station at the pier's end.

Lifts to all seven floors, a view from the Gravity Bar everyone can share, and a soft drink for the children where the grown-ups get the pint.

A big riverside restaurant in a former woollen mill beside the Ha'penny Bridge, with high chairs and a roomy dining room. Ask when booking about step-free tables.

Cobbles, the Campanile and benches under the trees in the 1592 college; the children chase pigeons while the grandparents sit.

Level paths, the warm Victorian glasshouses and benches by the river; bus 4 from O'Connell Street stops at the gate.

Soup, sandwiches and a slice of cake at a long table in the visitor centre, with the glasshouses through the window.

Francis Bacon's studio moved from London piece by piece, and a lift to the Harry Clarke window; free, close to the airport bus.
