A large abandoned area of Lisbon was redeveloped for the ´98 international expo´, so that it could later be converted and integrated into a special neighbourhood of the city featuring large leisure, entertainment and free-time facilities. This called for practical lighting serving ordinary urban purposes and “spectacular or playful” lighting designed to create a festive atmosphere, contribute to reading and enhancing architectural space, and focusing on the works of art on display. The paths, bridges, constructions built on water, landscaping and gardens, exhibition buildings, theatre, refinery tower in the south port, roads, service and rest areas, and, last but not least, the River Tejo and dock lands were the various themes guiding the choice of lighting designs and appliances. The project was intended to smoothly knit together light and landscape, light and visual functions, despite all the differences between the areas involved. The road lighting reverted to tall lampposts to create smooth lighting without too many appliances. The pedestrian ways were lit by oblique light with notable illuminance ratings, without using any appliances during the daytime and leaving an unblocked view of the skies at night. Special lighting was designed for the pavilions, bars and restaurants, parasols, fountains, waterways and banners, so as to make every single item´s forms and functions recognisable even from a distance at nighttime.
