Because The Legend of Zelda: Tears of the Kingdom places a heavy emphasis on sky exploration, Breath of the Wild's towers have all been replaced by Skyview Towers. These tall skyscrapers can launch Link high into the sky to ensure he not only gets a good lay of the land, but that he also reaches his destinations quickly and efficiently with his paraglider. While most of TotK's Skyview Towers are immediately available for use upon discovery, some of them require a bit more work before they're accessible.
