Lisbon's river was too salty to drink. King John V's answer, begun in 1731: a 14.2 km waterway whose full network of canals, galleries, and reservoirs stretches nearly 58 km. The centrepiece is the monumental arcade crossing the Alcântara valley, anchored by the Arco Grande — one of the tallest pointed masonry arches in the world.
What to look for
- The Arco Grande spanning the Alcântara valley — one of the tallest pointed masonry arches in the world
- 18th-century masonry that came through the 1755 Lisbon earthquake without significant damage
- The network's scale: 58 km of canals, galleries, and reservoirs spreading across the city
The arcade crossing the Alcântara valley is the main visual spectacle — position yourself in the valley for the full height of the arches.
