A curving, white-tiled building lying toward the river, its roof a walkable ramp. At the top you get the 25 de Abril bridge and the Tagus in one view. Next door the red-brick Central Tejo is a converted power station with the old machines still inside. The building is the main exhibit, and the roof alone is worth a stroll.
