Architect(s) : Manuel Graça Dias et Egas José Vieira

From the beginning of the Expo project, it was decided to keep the cracking tower of the former refinery as a vestige of this former industrial area.

As the most striking element of this entrance - the closest to the centre of Lisbon and the beginning of the central avenue of the exhibition site, and yet also an urban landmark of this future district, a new centre of the Lisbon metropolitan area.

The architects, Manuel Graça Dias and Egas José Vieira, created a walkway around this tower with artistic designs by Pedro Calapez, which extends over a curved ramp (lit at night) leading to the first level of the tower, a viewing platform.

For those arriving at EXPO '98, a strange architecture welcomes visitors. In reality, it is a pointed shape, guiding visitors to the ticket counters and turnstiles to enter the exhibition site via the circular walkway under the ramp, which is located right next to the cracking tower.


Using a 'before and after' approach, the architects have created a set of very diverse forms that represent today, and will represent tomorrow, the successive stages of the transformation of the dilapidated industrial area in the Dock Olivais, in this new and exemplary district of Lisbon.
