Lisbon Region covers Travelog's two Portuguese capital-area cities: Lisbon itself, where the 1983 UNESCO listing protects one specific riverside monument complex, and Sintra, a short trip away, where the 1995 listing protects an entire landscape of Romantic-era palaces and parks rather than a single building.
Lisbon and Sintra sit close enough together, roughly 30 kilometers apart, that many visitors see both on the same trip, but their UNESCO stories couldn't be more different: one protects a specific riverside monument complex, the other an entire hillside landscape of palaces built across a century of Romantic-era imagination.
