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

A flat square the size of a parade ground with benches under the arcades, the river steps and the cafés; everyone arrives at their own pace.

An hour of the city's story told sitting down, the earthquake in a 4D room; audio guides in every language and a lift to each floor.

Dinner at seven under the arcades: bacalhau for the elders, a steak for the rest, the oldest café in the city with the longest tables.

Everything on one loop around the big tank with benches and a lift; the penguins hold the eight-year-olds, the sea dragons the eighty.

A long table on the Pimenta promenade for grilled fish and salad, the river beside you and no steps anywhere.

The cable car for the view, eight minutes seated, gondolas that take pushchairs; then back to the hotel for the rest hour.

The Manueline nave is free and level, pews to rest in; the cloister ticket and its stairs are for the ones who want them.

The custard tarts in the tiled back rooms, which seat a family of ten faster than the takeaway queue outside suggests.

The royal coaches in a 2015 hall with lifts and ramps, forty minutes of gilt and a café at the end.

The 1885 funicular up from Restauradores, two minutes seated, to the garden terrace with the castle view and benches in the shade.

The plain Jesuit church with the chapel assembled in Rome from lapis and agate; a flat floor, and a pew for each generation.

Lunch in the tiled 1836 beer hall two doors down, big tables, big portions, and the Baixa-Chiado metro to the airport beneath it.
