Saldanha and Avenidas Novas are Lisbon's deliberate century — the grid the city laid out when it pushed north off its hills in the early 1900s, all broad avenues and confident apartment blocks. It's an architecture walk more than a pretty one, and it rewards looking up.
Start at Praça do Duque de Saldanha, the roundabout that anchors the district, and head north. The first stop is the best: the Casa-Museu Dr. Anastácio Gonçalves, an Art Nouveau house built for the painter Malhoa, now a quiet museum. Go for the building. Mind the Monday closure.
Then walk Avenida da República and read the façades as you go — Art Deco above the shopfronts, the whole self-assured early century on display. A detour west gets you the edge of the Gulbenkian gardens if you want green and shade; the museums can wait for their own day.
The walk lands at the Praça de Touros do Campo Pequeno — an 1892 bullring in neo-Moorish brick, onion-domed and improbable, now a venue as much as an arena. Circle it once. The metro is directly underneath.
