[8] With some influence from Gothic architecture, the station bears considerable resemblance to Santiago Calatrava's earlier Allen Lambert Galleria within Toronto's Brookfield Place.
Calatrava's objective was to realize a new space with ample room and functionality providing multiple connections between various zones in the metropolitan area of Lisbon.
The decision to elevate the rail line, for example, eliminated a physical barrier between the city and the Tagus River margin.
