Expo-led waterfront district
National-scale brownfield transformation
Parque das Nações transformed a derelict industrial stretch of Lisbon's eastern Tagus riverfront, previously occupied by refineries, a slaughterhouse and container depots, into a new mixed-use district built for the Expo '98 world exposition. Led by the state company Parque Expo with multiple design teams, the plan combined exhibition grounds with permanent infrastructure, including Santiago Calatrava's Gare do Oriente interchange, the Oceanário, a riverside park and subsequent housing and office quarters. It was conceived from the outset as a lasting piece of city rather than a temporary fairground.
The project became a widely cited European model of event-led brownfield regeneration, showing how a mega-event could be harnessed to deliver a permanent waterfront district at national scale. It reoriented Lisbon towards its river and influenced later expo and event-driven urbanism debates, including questions about the social exclusivity of the resulting district.
