The Praça do Comércio is Lisbon's royal sea gate: here stood the kings' palace two centuries until the 1755 quake and its tsunami swallowed it — and Pombal remade the site as a perfect yellow arcaded square opening its whole chest to the river: Europe's greatest water-joined plaza, José I in bronze on horseback at its heart. Through its triumphal arch (the Arco da Rua Augusta — ride to its roof on a small ticket for the square's complete angle) enters the lower Baixa: Pombal's straight grid, history's first modern earthquake planning, its streets named for the crafts, up to Rossio square with its famous wave pavement and twin fountains. And on the square's bank the Cais das Colunas — twin marble stairs descending into the Tagus where royal barges landed: sit on their stones as sunset burns the bridge: Lisbon's first evening rite, free.

Pombal answered with stern reason: the grid and anti-seismic rules as history's first earthquake engineering — the Lisbon you walk was born that morning.
