Lisbon spills down seven hills toward the Tagus estuary, a city of pastel facades, hand-painted azulejo tiles, and yellow trams that screech around corners barely wider than themselves. Settled by Phoenicians and reshaped by the Romans, the Moors, and a catastrophic 1755 earthquake that flattened the lower town, it carries layers of history you can read in its streets: the tangled medieval lanes of Alfama survived the quake, while the grid of Baixa rose from its rubble as one of Europe's first planned neighborhoods.

This is a city built for wandering, but the hills are real, so pace yourself and let the funiculars, the Santa Justa lift, and tram 28 do some of the climbing. The food is reason enough to come: salt cod served a hundred ways, grilled sardines in summer, custardy pasteis de nata still warm from the oven, and crisp vinho verde poured by the glass. Spring and early autumn bring the kindest weather, while June layers on the Santo Antonio street festivals, grilled-sardine smoke, and long golden evenings.

Getting around is easy and cheap: a rechargeable Navegante/Viva Viagem card works on the metro, buses, trams, and funiculars, and central neighborhoods are walkable if you accept the climbs. Lisbon is one of Western Europe's better-value capitals, friendly to a mid-range budget, though the most atmospheric fado dinners and the Sintra day trips reward a little advance planning. Three days is enough to fall for the place; you will leave already plotting a return.
