Vasco da Gama Tower
Without a doubt, the Vasco da Gama Tower (Torre Vasco da Gama) is among the more noteworthy landmarks in Parque das Nações, not only for its beautiful architecture but also as the tallest skyscraper in the city. Standing at 145 meters (475 feet) tall, it is a striking building, originally intended to be an observation deck but later converted into a luxury hotel. You will find it shining by the river behind Oriente Station. Unfortunately, only guests of the hotel are allowed onto the observation deck at the top.
