The creation of referential architecture with strong symbolism made available by the World Exposition constituted a central element of the Urbanisation Plan with its contribution to the regard for and the singularity and consolidation of urban space.

The following buildings received special importance in respect of their location and articulation with the urban structure – and which determined it to a large degree:

• TCC Tower (memory of its use).
• Oriente Station (metal and glass trees).
• Oceanarium - (theme of the Expo 98 – the Oceans/an anchored liner).
• Pavilion of Portugal ( covered public square / tent).
• Pavilions of the Exposition Centre (city of the imagination).
• Multi-Use Pavilion (hydroplane/space ship)
• Video-Stadium ( place of the unexpected / ephemeral place of invention).
• Panoramic Tower (sail ship / caravel).
