At the park's easternmost edge and rising 480 feet above it, the graceful, white Vasco da Gama Tower is Portugal's tallest structure. Three glass elevators whisk you up 345 feet to the observation deck. In addition to taking in vistas across Lisbon and the Atlantic Ocean, you'll feel as if you're eye to eye with the 18-km (11-mi) Ponte Vasco da Gama (Vasco da Gama Bridge). You could lunch up here in the restaurant, but its menu is on the pricey side.
